A simple, no-pectin strawberry jam recipe that sets naturally with the right sugar-to-berry ratio and safe water-bath canning.

Ingredients

Scale
  • 4 cups fresh strawberries, hulled and crushed
  • 2 cups granulated sugar
  • 1 tbsp lemon juice

Instructions

  1. Combine strawberries, sugar, and lemon juice in a large pot.
  2. Cook over medium heat, stirring until sugar dissolves.
  3. Bring to a boil, then reduce heat and simmer for 20-25 minutes until thickened.
  4. Test the jam by placing a small amount on a cold plate—if it gels, it’s ready.
  5. Ladle hot jam into sterilized jars, leaving 1/4-inch headspace.
  6. Process jars in a water bath for 10 minutes.
  7. Remove jars and let cool for 24 hours before storing.

Notes

  • Use ripe strawberries for the best flavor and natural pectin.
  • Adjust sugar slightly based on berry sweetness.
  • Store unopened jars in a cool, dark place for up to a year.
