Ingredients
Scale
- 4 cups fresh strawberries, hulled and crushed
- 7 cups granulated sugar
- 1 package Sure Jell fruit pectin (1.75 oz)
- ½ cup water
- 2 tbsp lemon juice (for acidity & preservation)
- 1 tsp unsalted butter (optional, reduces foaming)
Instructions
- Prepare the Ingredients: Wash and hull the strawberries. Crush them using a potato masher or food processor, leaving some texture.
- Sterilize Jars: Place canning jars in boiling water for 10 minutes to sterilize. Keep warm until ready to use.
- Cook the Jam: In a large saucepan, combine crushed strawberries and lemon juice. In a small bowl, mix Sure Jell pectin with ½ cup sugar, then stir it into the strawberry mixture. Heat over medium-high heat, stirring constantly until the mixture reaches a rolling boil.
- Add Sugar & Boil: Add the remaining sugar all at once, stirring continuously. Bring the mixture back to a full rolling boil (one that cannot be stirred down) and boil for exactly 1 minute.
- Skim Foam & Fill Jars: Remove from heat and skim off foam if necessary. Ladle hot jam into sterilized jars, leaving ¼-inch headspace.
- Seal & Process: Wipe jar rims clean, place lids, and screw bands on firmly. Process jars in a boiling water bath for 10 minutes to ensure proper sealing.
- Cool & Store: Remove jars and let them cool completely. Store in a cool, dark place for up to 1 year. Refrigerate after opening.
Notes
- Use ripe strawberries for the best flavor and natural sweetness.
- Do not alter the sugar amount, as it affects the jam’s ability to set.
- If jam is too runny after cooling, let it sit for 24-48 hours before reprocessing
