Kumquat and Cherry Jam

Rinse and stone the cherries. Rinse the kumquats in hot water, remove the stems, and thinly slice. Weigh the cherries and kumquats. You should have 1 kg (approximately 35 ounces) of fruit. Mix with the lemon juice and the jam sugar.

Set aside and let marinate for 2 hours. Bring to a boil slowly, stirring constantly. Cook for 4 minutes, stirring occasionally, until the jam begins to thicken.
