Best Three Citrus Marmalade Recipes

THREE-CITRUS MARMALADE

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.

SURE.JELL® THREE-CITRUS MARMALADE

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 half each of the orange and lime using a vegetable peeler. Cut removed peels into thin slivers. Place in 4-qt. saucepan. Add water and baking soda; mix well. Bring to boil on medium-high heat. Reduce heat to medium-low; cover and simmer 20 min. Remove and discard remaining colored and white parts of peels from the orange and lime. Finely chop the fruit, reserving any juice; set aside.
• Remove and discard colored and white parts of peel from the grapefruit; finely chop the fruit, reserving any juice. Add chopped grapefruit, orange and lime to peels in saucepan; cover and simmer 10 min. Measure exactly 4 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir pectin 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 sugar. 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.)
