Ingredients
Method
- Measure out raspberries and sugar. Wash and sanitize jars, rings, and lids. Prepare canner with water and heat to a simmer.
- Smash raspberries with a potato masher in a large kettle. Stir in sugar and heat over medium-high, smashing more as they cook.
- Bring mixture to 220°F (adjust for elevation) to reach the gelling point.
- Ladle jam into prepared jars, leaving ½ inch head space. Wipe rims, add lids and rings, and place in the canner.
- Process jars for 10 minutes in boiling water, then let cool in the canner for 5 minutes before removing.
- Let jars rest for 12 hours before storing.
