Equipment

  • saucepan

Ingredients

  • 1 pint blueberries or 2 cups of chopped strawberries
  • ¼ cup granulated sugar
US - Metric

Instructions

  • Cook the Fruit: Add the blueberries (or strawberries) and sugar to a medium saucepan. Cook over medium heat until the mixture begins to simmer. Gently mash the fruit with a potato masher or the back of a fork.
  • Stir the Mixture: Once it starts to boil, stir continuously to help the sugar dissolve and the fruit break down.
  • Cook and Thicken: Continue cooking, stirring occasionally, until the mixture thickens. This happens quickly.
  • Cool and Store: When the jam reaches a gel-like consistency, remove from heat. Let it cool completely, then transfer to a clean glass jar.

Notes

  • Use Pectin-Rich Fruit: Blueberries and strawberries work well because they naturally contain pectin.
  • Cook Low and Slow: Simmer for 20 to 30 minutes to allow the jam to thicken as moisture evaporates.
  • Check Consistency: Some fruits release more water. Start checking for doneness around the 20-minute mark.
  • Cut Fruit Evenly: Slice fruit into similar-sized pieces for even cooking.
  • Softer Texture Is Normal: Jam without added pectin will be softer than store-bought but has a fresher, more vibrant flavor.
