Grapefruit Jam 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:

• 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:

• If you want to have thin orange zest you have to soak zest from one orange 5 days changing water every 12 hours. After 5 days, cut the zest into thin slices.
• Squeeze out juice from orange and grapefruit. It should be aboput 2 liters of juice.
• Put orange zest, sugar and juice into pot and start to cook. After boils, cook on moderate fire about 15 minutes. In the meantime put glass-bottles into oven on 100°C
• After 15 minutes, add pectin in amount necessary for making jelly. Stir well 1-2 minutes making sure all pectin is dissolved.
• Than start to fill in the glass- bottles. Leave 1 inch space between jam and cover. Leave to cool it slowly.
