- Remove peel from 2 of the oranges; cut up peeled oranges and unpeeled orange. Coarsely grind all of the oranges and the peaches. (Or, use food processor to finely chop fruit.) Measure 6 cups fruit. Lightly coat an 8- to 10-quart kettle or Dutch oven with cooking spray. In kettle, combine ground fruit and sugar. Bring mixture to a full rolling boil; stirring often. (A full rolling boil does not stop when stirred with a wooden spoon.) Boil, uncovered, for 25 to 30 minutes or until marmalade sheets off a metal spoon.
- Remove kettle from heat; using a metal spoon quickly skim off foam.
- Ladle at once into hot, sterilized half-pint jars, leaving a 1/4-inch headspace. Wipe jar rims; adjust lids. Process in a boiling-water canner for 10 minutes (start timing when water begins to boil). Remove jars; cool on a rack until set. Makes 7 half-pints (ninety-four, 1 tablespoon servings).
From the Test Kitchen
To prepare the canning jars, wash them in hot soapy water; rinse thoroughly. To sterilize the jars, immerse them in boiling water for 10 minutes. Prepare lids and screw bands according to manufacturer's directions.
Fill canner half full of water; cover and heat over high heat until boiling. Heat additional water in another kettle.
When the water is hot, fill each jar and place it on rack in canner. Leave some space between the jars. After the last jar has been added, pour additional boiling water into canner until jars are 1 inch below the water line. Cover; heat to brisk, rolling boil. Now begin the processing timing. Keep the water boiling gently during processing.
At the end of processing time, turn off heat; remove jars. Cool on rack, wooden board, or towel. When jars are completely cool (12 to 24 hours), press the center of each lid to check the seal. If dip in lid holds, the jar is sealed. (The contents of unsealed jars can be refrigerated and used within two to three days or reprocessed within 24 hours. To reprocess, use a clean jar and a new lid; process for the full length of time specified.)
