Sure Jell Recipes: How to Make Perfect Jams & Jellies

This homemade strawberry jam recipe using Sure Jell pectin creates a sweet, perfectly set jam that’s bursting with fresh strawberry flavor. Ideal for spreading on toast, topping desserts, or gifting, this no-fail jam recipe is easy to make and delivers deliciously consistent results every time.

  • Total Time: 25 minutes
  • Yield: About 6 half-pint jars 1x

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

  1. Prepare the Ingredients: Wash and hull the strawberries. Crush them using a potato masher or food processor, leaving some texture.
  2. Sterilize Jars: Place canning jars in boiling water for 10 minutes to sterilize. Keep warm until ready to use.
  3. 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.
  4. 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.
  5. Skim Foam & Fill Jars: Remove from heat and skim off foam if necessary. Ladle hot jam into sterilized jars, leaving ¼-inch headspace.
  6. 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.
  7. 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
