Certo Lemon Marmalade Recipes

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain jars well before filling.
• Remove colored part of peel from oranges and lemons using vegetable peeler. Cut into thin slivers, finely chop or grind; set aside. Peel and discard remaining white part of peel from fruit. Chop fruit pulp, reserving any juice; set aside. Place peels, water and baking soda in saucepot. Bring to boil over high heat. Reduce heat; cover and simmer 20 min., stirring occasionally. Add reserved fruit and juice; cover. Simmer an additional 10 min. Measure exactly 3 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir sugar into prepared fruit in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

Steps:

• Cut the citrus: Using a sharp knife, slice off the top and bottom of the citrus so it sits sturdily on the cutting board. Slice off the peel and white pith in sections, starting at the top and following the curve of the fruit. (You should have a pile of peels and a few naked fruit.)
• Thinly slice the peels (with the pith) no thinner than 1/8 inch and no thicker than 1/4 inch, place them in a large bowl and set aside.
• Halve the fruit and remove any visible seeds. Thinly slice about 1/4-inch thick (white membrane and all), removing any seeds you might have missed. Add the fruit to the peels, and cover with 3 to 5 cups of water, taking note of how much water you used. Let this sit for at least 8 hours and up to 24 hours in the refrigerator. (This will help extract the pectin slowly as well as soften the peels.)
• Make the marmalade: Place a small plate in the refrigerator to chill. (You'll use this later.)
• Place the peels, fruit and water in a large pot. Add enough water to bring the total to 6 cups and bring to a strong simmer over medium-high heat.
• Cook the citrus until the peels have begun to soften and turn translucent, and the liquid has reduced by about three-fourths, 40 to 50 minutes.
• Add sugar and any add-ins and continue to cook, stirring occasionally at first, then more frequently as the marmalade cooks and the juices thicken. Continue until most of the liquid has evaporated and the peels are totally softened and almost completely translucent, another 40 to 50 minutes.
• As the marmalade cooks, the liquid reduces, the sugars thicken and the natural pectins activate. You'll notice the liquid go from a rapid, rolling boil with smaller bubbles to a slow, thick, tarlike boil with larger bubbles: This is the stage at which it's most important to stir constantly along the bottom of the pot to prevent scorching and sticking. (Sugar is heavier than water and will concentrate at the bottom of the pot, making the fruit more likely to burn.) It's also the stage at which splattering may occur, so take care in stirring.
• When the marmalade reaches this point, add lemon juice and continue to cook, stirring constantly until the jam has returned to its previously thickened state, about another 5 minutes. At this stage, the mixture should look thick and viscous with bits of the peel floating around. The peels will never break into the liquid as with a jam: This is O.K.
• To test the jam's thickness, spoon a bit onto the chilled plate, return it to the refrigerator and chill for 2 minutes. Drag your finger through it: It should hold its shape on either side without appearing watery or runny. If it's not there yet, cook it for a few more minutes.
• Remove from heat and discard the vanilla bean, if used. Divide among jars, leaving 1/4 inch of space at the top, and seal immediately. Can the marmalade (our How to Make Jam guide has detailed instruction), or store in the refrigerator.

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain jars well before filling.
• Remove colored part of peel from lemons using vegetable peeler. Cut into thin slivers, finely chop or grind; set aside. Peel and discard remaining white part of peel from fruit. Chop fruit pulp, reserving any juice; set aside. Place peel, water and baking soda in saucepot. Bring to boil on high heat. Reduce heat; cover and simmer 10 min., stirring occasionally. Add reserved fruit and juice and 1 cup of the sugar to peel mixture; cover. Simmer 20 min., stirring occasionally. Measure exactly 3-1/2 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir remaining 5 cups sugar into fruit mixture in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

Steps:

• Put a small plate into the freezer for testing the jam later. Scrub and dry the citrus. With a vegetable peeler, strip the zest (the outermost layer of the rind) from 1 orange, 2 blood oranges, and 2 Meyer lemons. Slice the strips into thin matchsticks about 1/16th inch in width. Add the strips to a small pot and cover with cold water. Over high heat, bring the pot to a boil and boil for 30 seconds. Drain the strips, rinse with cold water, and set aside.
• Cut both ends of each fruit. Using the side of your knife, remove the white pith and peel of each fruit. Discard the peels. Cut the fruit into quarters, removing any seeds or hard, pithy centers. Chop each fruit into roughly 1-to-2-inch pieces, saving all of the juice that drips onto the cutting board.
• Measure the fruit and any remaining juice (you should have about 6 cups.) Transfer to a medium heavy-bottomed pot. Add 6 cups water to the pot with the fruit and bring the mixture to a boil over high heat.
• When the mixture comes to a boil, lower the heat to medium. Cook fruit syrup, uncovered, for 1 hour, or until it has reduced by half. Periodically skim off white foam that accumulates at the top, and stir occasionally.
• Add the blanched zest and the sugar to the pot. Stir to combine, increase the heat to high, and bring the mixture to a boil. Reduce the heat to medium, and cook, about 10 minutes. The mixture should be at a bubbling simmer. After 10 minutes begin to stir the marmalade constantly. Cook for about 20 minutes more.
• The marmalade is ready when it is thick enough that a spoon leaves a trail at the bottom of the pan.
• Remove the plate from the freezer. Test the marmalade by placing a spoonful of it on the plate. It should thicken promptly. Prepare an ice water bath.
• Carefully pour marmalade into a medium bowl, scraping any bits with a spatula. Set the bowl into an ice water bath. Let cool slightly, stirring, about 5 minutes. Cover surface with plastic wrap and let cool completely. Store in airtight containers in the refrigerator for up to 2 weeks.

Steps:

• Chill a saucer in the freezer, ready for checking the setting point of your jam. Wash the lemons and remove the top 'button' which would have been attached to the stalk. Put the lemons in a large saucepan with 2.5 litres water. Bring to the boil, then cover the pan and simmer for 2½ hrs or until the lemon skins are lovely and tender, and can be pierced easily with a fork.
• When the lemons are cool enough to handle, remove from the saucepan. Measure the cooking liquid - you'll need 1.5 litres in total. If you don't quite have this, make up the difference with water. If you have too much liquid, bring to the boil and reduce to the required amount.
• Halve the lemons and remove the pips - reserving the pips and any lemon juice that oozes out during the process. Cut the lemon peel and flesh into strips, as thick or thin as you like. Put all of this, including any juices, back into the pan. Put the pips in a small piece of muslin and tie up with string. Add this to the pan, as the pips will aid the setting process of the jam.
• Add the sugar and bring to the boil, stirring until it has completely dissolved. Boil rapidly for about 20 mins until setting point is reached. Test the setting point by dropping a little marmalade onto the chilled saucer, allowing it to cool for 1 min, then pushing gently with your finger. If the marmalade crinkles, the setting point is reached; if not, continue to boil and check again in a few mins.
• Leave to cool for 10-15 mins (this will prevent the lemon shreds sinking to the bottoms of the jars), remove the muslin bag, then gently stir in one direction to disperse any scum (small air bubbles on the surface). Pour jam into warm sterilised jars and seal straight away.

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain well before filling.
• Cut orange and lemon into quarters; remove and discard seeds. Grind, finely chop or cut fruits crosswise into very thin slices. Mix ground fruit, water and lemon juice in saucepan. Cover and simmer 20 min., stirring occasionally. Peel and pit peaches; finely chop or grind peaches. Add to cooked fruit; mix well. Measure exactly 4-1/2 cups of the fruit mixture into 6- or 8-qt. saucepot.
• Stir sugar into prepared fruit in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

Steps:

Reduce heat; cover and simmer 5 minutes or until peel is softened. Remove from heat and set aside., Trim white pith from reserved lemons and grapefruit; discard pith. Cut lemons and grapefruit into segments, discarding membranes and seeds. Chop pulp, reserving juices; stir into reserved peel mixture., Add pectin. Bring to a full rolling boil over high heat, stirring constantly. Stir in sugar; return to a full rolling boil. Boil and stir 1 minute., Remove from heat; skim off foam. Ladle hot mixture into six hot half-pint jars, leaving 1/4-in. headspace. Wipe rims. Center lids on jars; screw on bands until fingertip tight., Place jars into canner with simmering water, ensuring that they are completely covered with water. Bring to a boil; process for 10 minutes. Remove jars and cool.

Steps:

• Note that the proportion of lemon segments to water to sugar is 1:1:1. So if you don't have a kitchen scale and don't weigh your lemons to begin with, as you proceed through this recipe keep in mind these proportions. Your 2 1/2 lbs of lemons should yield 6 cups of chopped lemon. 6 cups of chopped lemon will be cooked first with 6 cups of water, and then later 6 cups of sugar are added. You can also do this recipe with 4 cups of chopped lemons, 4 cups of water, and 4 cups of sugar. Do not double the recipe. Do not reduce the sugar (if you want a reduced sugar recipe, use a different recipe); the sugar is needed for the jelly to set.
• PREPARING THE FRUIT.
• Scrub the lemons clean. Discard any that are moldy or damaged.
• Prepare the lemons. Cut 1/4 inch off from the ends of the lemons. Working one at a time, stand a lemon on end. Cut the lemon in half lengthwise. Cut each lemon half into several segments, lengthwise. As you cut the lemons into segments, if you can, pull off any exposed membranes. Just get the ones that are easy to get to, ignore the rest. When you've cut down to the final segment, cut away the pithy core. Remove all seeds from the segments. Reserve the seeds and any removed membrane or pith. You will need them to make pectin. Cut each lemon segment crosswise into even pieces to make little triangles of lemon peel and pulp.
• Put all of the seeds, membranes and pith you removed from the lemons into a bag fashioned out of two layers of cheesecloth or a muslin jelly bag.
• FIRST STAGE OF COOKING.
• Place the lemon segments and water into a large, wide pot.
• Place the pectin bag in the pot with the fruit pulp and secure to the pot handle.
• Bring mixture to a medium boil on medium high heat. Let boil, uncovered, for about 25-35 minutes, until the peels are soft and cooked through. Test one of the lemon peel pieces by eating it. It should be soft. If it is still chewy, keep cooking until soft.
• Remove from heat.
• Remove the pectin bag, place the pectin bag in a bowl and let cool until it is comfortable to touch.
• ADD THE PECTIN AND SUGAR.
• Once your pectin bag has cooled to the point you can handle it, if you want, squeeze it like play-doh to extract any extra pectin. This is not necessary but will help ensure a good set. (I like to wear latex-type gloves for this part.) You should be able to get a tablespoon or two more from the bag. It has the consistency of sour cream. Return this pectin to the pan with the lemon mixture.
• Measure out your sugar and add it to the pan with the lemon mixture.
• SECOND STAGE OF COOKING.
• Heat the jelly mixture on medium high and bring it to a rapid boil. Secure a candy thermometer to the side of the pan. The marmalade may take anywhere from 20 to 35 minutes or so to be ready to pour out. After about 15 minutes, start checking it frequently.
• There are two ways to test that the marmalade is ready to pour out into jars - the mixture reaching a temperature of 220-222°F (8-10°F above the boiling point at your altitude) and a bit of it put on a chilled plate "wrinkling up" when you push it with your finger tip. I do both.
• For the wrinkle test, put several small plates into the freezer. As the jelly temperature reaches 218°F, start testing it by placing a small amount of the hot jelly on a chilled plate. If the jelly spreads out and thins immediately, it isn't ready. If it holds its shape a bit, like an egg yolk, that's a good sign. Push up against it with your finger tip. If the jelly sample wrinkles at all, it is time to take the jelly off the heat and pour it out into jars.
• When you use a candy thermometer to test the temperature of your mixture, make sure the probe is NOT touching the bottom of the pan. Make sure that the indentation on the probe (with modern candy thermometers this is about an inch and a half from the bottom of the probe) is actually surrounded by the mixture. This may mean that you have to tilt the pan to one side, to cover the probe sufficiently to get a good reading.
• CANNING.
• While the marmalade is in its second cooking stage, rinse out your canning jars, dry them, and place them, without lids, in a 200°F oven. They should be in the oven at least 10 minutes before using them.
• As the time approaches for the marmalade to be done, boil some water in a tea pot. Put the jar lids in a glass or ceramic bowl and pour the boiling water over them to sterilize.
• Once the jelly has reached 220°F or its "wrinkly" stage, remove the jelly pot from the heat. Carefully ladle the jelly into the jars, one at a time, leaving 1/4 inch head space at the top of the jars for a vacuum seal. Wipe the rim clean with a clean, wet paper towel. Place the lid on the jar, securing with a jar ring. Work quickly.
• Allow the jars to sit overnight. You will hear them make a popping sound as a vacuum seal is created.
• Even if the jelly is not firm as it goes into the jar (it shouldn't be), it should firm up as it cools.
