Grapefruit Marmalade Recipes

Steps:

• Inspect two 5-ounce jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until marmalade is ready. Wash new, unused lids and rings in warm soapy water.
• Thoroughly wash and dry the grapefruits. Run a zester around 2 grapefruits to produce ribbons of zest. Set aside. Cut away thin strips of peel from the other two grapefruits with a sharp paring knife.
• Peel off all remaining outer white parts of the fruit and discard. Cut the grapefruits into wheels. Remove any seeds.
• Put grapefruit wheels and zest strips into a non-reactive saucepan. Add sugar and stir well to cover fruit. Heat over medium-high heat until bubbling, mixing constantly. Smash the heated fruit until it liquefies. Reduce heat to low and cook over a steady boil, stirring often. Remove and discard any persistent white froth that won't disappear after being stirred. Continue to cook for about 10 minutes until marmalade begins to coat the back of a spoon.
• Add zest ribbons and cook for 5 minutes more. Place a small amount of marmalade on a plate and put it in the freezer. Test the consistency after 3 minutes.
• Remove the marmalade from the heat when the freezer sample meets your desired consistency.
• Pack grapefruit jam into hot, sterilized jars, filling to within 1/4 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 10 minutes.
• Remove the jars from the stockpot and let rest, several inches apart, for 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area.

Steps:

• Using a sharp knife, remove peel and white pith from 1 grapefruit and thinly slice. Remove peel and white pith from remaining grapefruit and discard (you won't want all of the peel and pith in the marmalade). Slice flesh of both grapefruits into rounds; remove any seeds.
• Combine sliced peel, grapefruit, and star anise in a large saucepan; scrape in seeds from vanilla bean and add pod. Toss to combine; pour in 4 cups water and bring mixture to a boil. Reduce heat and gently simmer until reduced by three-quarters, about 1 1/2 hours. Add sugar, return to a simmer, and cook until mixture is thickened and juices are syrupy (mixture will set up when a small amount is spooned onto a cold plate), 1-1 1/2 hours longer.
• Let marmalade cool slightly, then stir in lemon juice. Spoon into clean jars and let cool.
• Do Ahead
• Marmalade can be made 2 months ahead. Cover and chill.

Steps:

• In a large pot, place the two grapefruit in just enough water to make them float freely.
• Bring to a boil, and let boil for two hours (add water from a kettle if too much boils away and the grapefruit touch the bottom).
• Drain the grapefruit, discard water and let fruit cool (or else you'll burn your hands!).
• Slice the grapefruit as finely as possible, and chop a bit. This is tedious, but not difficult. It doesn't have to be uniform.
• Chuck the grapefruit, sugars and lemon juice back into the pot, and dissolve the sugars on low heat.
• Bring to a boil and let bubble until you reach the jell point, about 15 minutes, give-or-take.
• If you like a smoother consistency, blitz in a blender for a bit until you like what you see.
• Ladle into clean, sterilized jars and process in a hot water bath for ten minutes.

Steps:

• Slice the grapefruit very very thinly with a sharp knife, into flat slices. then cut these into strips, and cut the strips into smaller bits. Keep all the juice that flows out, if it's a juicy grapefruit.
• Bring 6 cups of water to a boil, and then add the grapefruit slices and juice.
• Keep at a low boil, adding the sugar. Continue boiling for quite some time (20-30 minutes), until it begins getting thicker.
• The tricky part is knowing when to stop boiling. If you wait too long, it will become too thick when it cools. The important thing to know is it thickens a bit when cooling, so you have to stop it before it reaches the desired consistency. I put a porcelain dish in the fridge, then pour a little onto the dish - if it congeals a little, then it's ready.
• Before you bottle it, eat it with bread while it's still warm - it's delicious!
• Pour in any clean bottle, and refrigerate.

Steps:

• Cut fruit in half, squeeze out juice and pulp, discard seeds. The volume of this should be approximately 4 cups. Remove zest, this should yield approximately 1/2 cup. Transfer juice, pulp and zest to a large glass bowl. Cover and refrigerate for 24 hours. This helps the peel to soften.
• After soaking, put the citrus in a large stockpot. Add 6 cups of water, simmer for 1 1/2 hours. A sample of the peel should feel quite tender if rubbed between fingers. Add sugar and ginger. Bring to a boil, stirring constantly with a wooden spoon. Boil hard for 20 minutes until sugar is dissolved and mixture is thickened. If the mixture foams up, add a pat of butter and the froth will subside.
• Test for jell-point: drop a small amount of hot marmalade on a chilled plate. Return to the freezer for 1 minute. If surface forms a skin, it has reached jelling point, if still syrupy, continue cooking and test again in 5 minutes.
• Remove from heat, stir in pectin. Cool for 15 minutes, spoon into half-pint sterilized jars leaving 1/4-inch headspace and seal.
• ** Recipe Note: Traditionally the citrus seeds and pith are enclosed in a nylon bag and boiled along with the juice/pulp. This releases the natural pectin that is stored in that part of the orange. For time and ease, we eliminated that step and used store-bought fruit pectin. It worked very well.
• ***To sterilize the canning jars, wash the containers in hot, soapy water and rinse. Boil them in a large pot for 10 minutes. Keep the jars in hot water until ready to use to prevent the jars from cracking. Dry with paper towels before filling with marmalade. Once filled, put on lids and collar. Boil again for 10 minutes to seal the jars.
