Chill a small plate or bowl in the freezer or over ice water.

In a 10 or 12-inch wide skillet, bring fruit, sugar, and lemon juice to boil over medium-high heat, stirring occasionally.

Reduce heat to medium and cook, stirring constantly and skimming foam as necessary. Cook about 8-10 minutes, until mixture begins to look syrupy and thickens slightly.

Spoon ½ teaspoon of the hot fruit onto the cold plate and let it rest for 30 seconds. Tip plate to one side; jam should be a soft gel that moves slightly. If mixture is thin and runs down side of plate, the gel is too soft. Return skillet to heat and cook jam 1 to 2 minutes longer, stirring constantly. Remove from heat and repeat test.

Cool jam to room temperature before serving. Because a minimum amount of sugar is used, the jam needs to be refrigerated to prevent mold from forming. Refrigerate 2-3 weeks.

For longer storage, freeze or process hot jam in a boiling water canner for 10 minutes.**

**Option: If jars are sterilized (heated in boiling water for 10 minutes) it’s possible to use the inverted method to preserve jam: Pour hot jam into hot sterile jar leaving 1/8 inch head space. Wipe rim and apply prepared lid and ring. Screw ring on firmly. Invert jar and leave for 5 minutes. Turn jar right side up and let cool 12-24 hours. The heat from the jam will destroy mold spores. This method is not foolproof, so if you are preparing a lot of jam, process the jam in a boiling water canner.
