2 pounds navel oranges, preferably organic
1 cup sugar
Juice one pound of the oranges. Add water as needed to measure ¾ cup.
Scrub and rinse the remaining pound of fruit. Cut it into one inch pieces and pulse 3 or 4 times in the work bowl of a food processor. Add the juice and run the machine briefly to create a rough fruit mash.
Simmer this mixture over medium-low heat for 10 minutes, stirring regularly, and measure again. The volume will have reduced to half after cooking. Measure and set aside the same volume of sugar.
Set the orange mixture over medium heat in a clean saucepan and add the sugar in ½ cup increments, waiting for the liquid to return to the boil before adding the second half. Once all the sugar is added, cook another 5 minutes. Stirring regularly. The preserve should fall from a metal spoon in a thick stream. A tablespoon of marmalade refrigerated on a small plate will cool to a firm consistency.
Off the heat, pour the marmalade into the measuring cup and hold for 5 minutes, stirring to evenly distribute the fruit pieces throughout the preserve. Pour into clean jars with tightly fitting lids and cool on a rack. Refrigerate between uses.
Instructions for vacuum sealing jars for storage at room temperature are in Artisanal Preserves.
