ORANGE JAM NOT MARMALADE RECIPES

Steps:

• Cut the oranges and lemons in half crosswise, then into very thin half-moon slices. (If you have a mandoline, this will be quite fast.) Discard any seeds. Place the sliced fruit and their juices into a stainless-steel pot. Add 8 cups water and bring the mixture to a boil, stirring often. Remove from the heat and stir in the sugar until it dissolves. Cover and allow to stand overnight at room temperature.
• The next day, bring the mixture back to a boil. Reduce the heat to low and simmer uncovered for about 2 hours. Turn the heat up to medium and boil gently, stirring often, for another 30 minutes. Skim off any foam that forms on the top. Cook the marmalade until it reaches 220 degrees F on a candy thermometer. If you want to be doubly sure it's ready, place a small amount on a plate and refrigerate it until it's cool but not cold. If it's firm -- neither runny nor too hard -- it's done. It will be a golden orange color. (If the marmalade is runny, continue cooking it and if it's too hard, add more water.)
• Pour the marmalade into clean, hot Mason jars; wipe the rims thoroughly with a clean damp paper towel, and seal with the lids. Store in the pantry for up to a year.

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. Mix the peels, water and baking soda in large saucepan. Bring to boil. Reduce heat to medium-low; cover and simmer 20 min., stirring occasionally. Add the fruit and juice. Cover and simmer an additional 10 min. Measure exactly 4 cups prepared fruit into 6- or 8-qt. saucepot.
• Stir pectin 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 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 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.)
