  • 3 pounds fresh tomatoes washed and dried, stemmed and cut into large chunks
  • 1/2 cup yellow onion, finely chopped
  • 2 approximately (3-inch) serrano chile peppers, stems, seeds and membranes removed
  • 1/2 cup granulated sugar (see notes)
  • 2 tablespoons freshly squeezed lime juice


  1. Add the tomatoes, onion and peppers to a medium-sized sauce pot.
  2. Sprinkle with the sugar and drizzle with the lime juice. Mix well and turn the heat to high.
  3. Bring to a boil and then immediately turn the heat to low and let it simmer gently until it's nicely thickened, about 2 hours.
  4. Let the preserves cool completely before refrigerating. (Wrapped tightly, this will keep in the refrigerator for about 3 weeks.)

Recipe Notes

In the middle of the summer, tomatoes should be super sweet, so less sugar is needed. If at the end of the cooking time, it's not sweet enough for you, you can add more sugar, and let it cook a bit longer. (I've used up to 1 cup.)

If you find yourself with tons of tomatoes, make as much of the preserves as you can at once! Here is a guide to Sterilizing Jars for Preserves.
