Raspberry Jam

Unopened jars keep for 1+ years in a cool, dark pantry. Once opened, refrigerate and use within 3–4 weeks. Freezer storage extends life up to a year if frozen in airtight containers or ice cube trays.

Stir jam before using if sugar crystals have settled at the bottom.

If jam has mold on top, discard the entire jar for food safety.

A thin layer of melted paraffin wax or plastic wrap pressed onto the surface helps preserve opened jars longer.

For homemade jam, use a rolling boil and test for set by dropping a spoonful on a cold plate—it should wrinkle slightly when pushed.

Add lemon juice to homemade jam for brighter flavor and better gel.

Toast, croissants, and pastries

Yogurt and oatmeal

Cheese boards (pairs well with brie, goat cheese, cream cheese)

Vanilla ice cream and desserts

Baked goods like muffins, scones, and jam tarts

Glazes for duck, ham, or pork

Using too much sugar or too little—both affect texture and shelf life.

Overcooking jam, which makes it hard and bitter.

Not sterilizing jars properly before canning, risking spoilage.

Sealing jars while still warm; let them cool first or use proper canning technique.
