Citrus Tomato Marmalade Recipes

Steps:

• If desired, sterilize jars , lids, and screw bands.
• Chill 2 small plates (for testing marmalade).
• Cook all ingredients, including reserved juices from tomatoes, in pot over moderate heat, stirring frequently, until sugar is dissolved, about 6 minutes. Simmer, stirring frequently as marmalade thickens (to prevent scorching) and adjusting heat as needed, until marmalade tests done, 50 minutes to 1 1/4 hours. Begin testing for doneness after 50 minutes: Drop a spoonful of marmalade on a chilled plate, then tilt; it should remain in a mound and not run (if necessary, remove pot of marmalade from heat while testing).
• If not processing, cool marmalade, uncovered, then chill in an airtight container (preferably glass).
• If processing, drain jars upside down on a clean kitchen towel 1 minute, then invert. Ladle marmalade into jars, leaving 1/4 inch of space at top. Run a thin knife between marmalade and jar to eliminate air bubbles.
• Seal, process, and store filled jars (and boil marmalade in jars 10 minutes).
• Let marmalade stand in jars at least 1 day for flavors to develop.

Steps:

• Cut tomatoes into small pieces, drain.
• Slice oranges and lemons very thin; quarter the slices.
• Tie cinnamon sticks and cloves in cheesecloth bag.
• Place tomatoes in large kettle, add sugar and salt and stir until dissolved.
• Add oranges, lemons and spice bag.
• Boil mixture rapidly, stirring constantly until thick (about 50 minutes).
• Remove from heat; skim foam.
• Pour into 1/2 pint jars and seal.
• Process 5 minutes in boiling water bath.
• Recipe can be halved.

Steps:

• REMOVE peel from tomatoes and cut in small pieces.
• Slice oranges and lemons very thin and quarter the slices.
• Pour off juice from the tomatoes.
• Add sugar.
• Stir until the sugar is dissolved.
• Add oranges, lemons, and spices which have been tied loosely in cheesecloth bag.
• Place mixture over high heat and boil rapidly, stirring often.
• Cook until clear and thick (about 50 minutes).
• Pour into sterilized jars to within 1/2 inch of top.
• Put on cap, screw band firmly tight.
• Process in Boiling Water Bath 10 minutes.

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:

• Day 1
• First, prepare the lemon and orange slices: Place the slices in a wide stainless-steel kettle and cover amply with cold water. Bring to a boil over high heat, boil for 1 minute, and then drain, discarding the liquid. Return the slices to the kettle and cover with 1 inch cold water. Bring to a boil over high heat, then decrease the heat to medium and cook, covered, at a lively simmer for 30 to 40 minutes, or until the fruit is very tender.
• While the citrus is cooking, prepare the tomatoes: Bring a medium kettle of water to a boil, then carefully drop the tomatoes into the water to loosen their skins. Leave the tomatoes immersed for 1 minute, then drain them in a large colander. When they are cool enough to handle, peel them over a large bowl, discarding the skins. Using your hands, gently tear the tomatoes into medium pieces.
• When both the citrus slices and tomatoes are ready, put them together into a nonreactive heatproof storage container with the sugar, lemon juice, and saffron, stirring well to combine. Cover tightly and refrigerate overnight.
• Day 2
• Place a saucer with five metal teaspoons in a flat place in your freezer for testing the marmalade later.
• Remove the tomato mixture from the refrigerator and transfer it to an 11- or 12-quart copper preserving pan or a wide nonreactive kettle. Add the cinnamon stick and stir well to incorporate any undissolved sugar.
• Bring the mixture to a boil over high heat. Cook at a rapid boil until the setting point is reached; this will take a minimum of 30 minutes, but may take longer depending on your individual stove and pan. Initially, the mixture will bubble gently for several minutes; then, as more moisture cooks out of it and its sugar concentration increases, it will begin to foam. Do not stir it at all during the initial bubbling; then, once it starts to foam, stir it gently every few minutes with a heatproof rubber spatula. As it gets close to being done, stir it slowly every minute or two to prevent burning, decreasing the heat a tiny bit if necessary. The marmalade is ready for testing when it turns slightly shiny and its bubbles become very small.
• To test the marmalade for doneness, remove it from the heat and carefully transfer a small representative half-spoonful to one of your frozen spoons. It should look glossy, with tiny bubbles throughout. Replace the spoon in the freezer for 3 to 4 minutes, then remove and carefully feel the underside of the spoon. It should be neither warm nor cold; if still warm, return it to the freezer for a moment. Tilt the spoon vertically to see whether the marmalade runs; if it does not run, and if its top layer has thickened to a jelly consistency, it is done. If it runs, cook it for another few minutes, stirring, and test again as needed.
• When the marmalade has finished cooking, turn off the heat but do not stir. Using a stainless-steel spoon, skim off any surface foam and discard. Remove the cinnamon stick. Pour the marmalade into sterilized jars and process according to the following instructions.
• Sterilization & Storage
• When making preserves, be sure to sterilize your jars and lids, unless you plan to eat your jam right away. Although jams and marmalades are unlikely to become contaminated with anything toxic, it is important to eliminate even the minutest risk.
• There are many ways to sterilize jars, including putting them in a canning kettle or a sterilizing dishwasher, but my preferred way is in the oven. This method is easier than the other methods and, if you use an oven thermometer, is virtually foolproof. To sterilize jars and lids in the oven, first be sure they are perfectly clean. Place the clean jars upright with an equal number of clean unused lids on a baking sheet or sheet pan in a preheated 250°F oven. They should remain in the oven for a minimum of 30 minutes to ensure they are heated through. Remove them from the oven right when you need to fill them. After you have filled them, leaving 1/4 inch of room at the top, wipe the rims with a clean, damp cloth. Put the lids on, being careful to screw them on just until they are snug, and replace the jars in the oven for 15 minutes or so to ensure they are completely sterilized. They will seal as they cool.
• Sometimes the jars can become a little bit too hot when using this method, so before filling them, test their temperature first. Pour a little jam into one, and if it bubbles or boils in the jar, wait a few moments before filling the jars.
• Upon removing your filled jars from the oven, place them 1 inch apart on a drying rack to set overnight at room temperature. Do not jiggle or disturb them during this time, as this may disrupt their ability to set correctly. As the preserves cool, you may hear a few little pops as the lids seal. Before putting your preserves away, be sure to feel the top of each lid to verify that it has sealed; it should be curving in very slightly in the middle. If any jars have not sealed, put them in the refrigerator for safekeeping.
• To store sealed preserves, label and date them and keep them in a cool, dark place until you open them. After you open a jar, keep it in the refrigerator. You may also keep higher-sugar preserves at room temperature, assuming you plan to eat them within a few weeks or so. Low-sugar preserves should always be refrigerated once opened, unless you plan to consume them right away.

Steps:

• Chill a saucer in the freezer, ready for checking the setting point of your jam later. Wash the citrus fruits and remove the top parts that were attached to the stalks.
• Put the whole citrus fruits in a large saucepan with 2½ litres of cold water. Bring to the boil, then cover the pan and simmer for 2 hrs 30 mins, or until the skins can be pierced easily with a small knife.
• Use a slotted spoon to scoop the fruits out of the liquid and set aside to cool for at least 10-15 mins. Measure out 1.5 litres of the liquor and pour it back into the pan. If you don't have enough, top up with water.
• Halve the citrus fruits, remove the pips and set aside. Cut the peel and flesh into thin 0.2 cm strips (depending on how thick-cut you would like it to be). Tip all of the flesh and skin, along with any juices, back into the pan with the liquid. Put the pips in a small piece of muslin and tie up with string. Add this to the pan as well, which will help the setting process.
• Tip in the sugar and bring to the boil, stirring frequently. Continue to boil rapidly for 45-50 mins - it should reach 105C. Test the setting point by dropping a little marmalade onto the chilled saucer, allowing it to cool for 1 min, then push gently with your finger. If it crinkles, it has reached the setting point. If it doesn't, continue to boil and check again after 5-10 mins.
• Leave the marmalade to cool in the pan for 10-15 mins, then carefully scoop out the muslin bag using a slotted spoon. Gently stir the marmalade in one direction to disperse any air bubbles, then pour into sterilised jars and seal with a lid. Find out how to sterilise jars. Will keep for up to a year.

Steps:

• In a small bowl whisk all ingredients. Chill until serving.

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:

• Mix ingredients until blended.

Steps:

• Peel, quarter and chop the tomatoes; place in a colander to drain. Transfer to a Dutch oven; add apples and lemons. Cook and stir over medium heat for 15 minutes. Add sugar and ginger. Tie cloves in a cheesecloth bag; add to the pot. Bring to a boil, stirring occasionally, and cook until sugar has dissolved. Reduce heat; simmer for 40 minutes, stirring frequently., Remove spice bag. Carefully ladle hot mixture into nine hot half-pint jars, leaving 1/4-in. headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot mixture. 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.
