  • 1 cup berries (raspberries, blueberries, blackberries, or a mix) rinsed
  • 0.25 tsp corn starch

  2. Cover the bowl with a dinner plate, and microwave for 3 minutes. Give it a stir. If your jam is still very runny, pop it back into the microwave for 30 second intervals. Be careful, it will get quite hot.
