Lemon (citrus) Jam

Makes 2 jars worth

5 lemons (or 3 oranges or 1 grapefruit)1 ½ cups sugar

Cut citrus into quarters, and then put into a food processor fitted with the steel blade and pour the sugar on top. Pulse the citrus and sugar together until there are no pieces larger than a garbanzo bean. Fish out any seeds.

Transfer mixture to a medium pot and cook it over medium heat, stirring occasionally, until it is bubbling and thickened and reaches 220°F, about 10 minutes. 

Cool completely before using. It will keep in the refrigerator in an airtight container, for up to 1 month.
