Ingredients
Jam Ingredients
- 30 ounces raspberries (fresh or frozen)
- 3 ½ cups white sugar
- 5 tablespoons lemon juice (about ⅓ cup minus 1 teaspoon, or 2.5 fluid ounces)
Instructions
- Get prepped: Prepare your workspace by setting out all ingredients and ensuring you have 2 clean 16-ounce jars ready with lids for storing the finished jam.
- Measure ingredients: Accurately measure 30 ounces of raspberries, 3 ½ cups of white sugar, and 5 tablespoons of lemon juice to have them ready.
- Cook the jam: Place the raspberries, sugar, and lemon juice into a large pot over medium heat. Stir often as the raspberries soften and the sugar dissolves. Mash the berries gently to help them break down.
- Boil the jam: Increase the heat to medium-high and bring the mixture to a boil. Continue to cook and stir often for 7-9 minutes until the jam reaches 220°F (104°C).
- Finish cooking: Maintain the boil for an additional 3 minutes, stirring constantly to prevent scorching on the pot bottom.
- Jar and cool: Carefully ladle the hot jam into the clean jars, cover with lids, and let them cool at room temperature. Once cooled, refrigerate the jars.
- Set the jam: Allow the jam to rest for 12-24 hours in the refrigerator to fully set before consuming.
Notes
- Use fresh or frozen raspberries according to availability; frozen raspberries may require slightly longer cooking time.
- Ensure jars are sterilized and dry to avoid spoilage.
- Do not skip stirring frequently to prevent the jam from burning.
- The jam should reach 220°F (104°C) to properly set; using a candy thermometer is recommended.
- Jam can be stored in the refrigerator for up to 3 weeks or frozen for longer storage.
