Ask anyone in my house or social circle what the big culinary wonder was last summer, and they’ll all tell you: “Fermented salsa!”. Far removed from the cooked salsa in jars, fermented salsa is like a tangy, juicy version of the popular pico de gallo type of dip. This was a technique I learned about years ago on a homestead in Maine, but started preparing last summer when faced with a constant glut of tomatoes and absolutely no desire to turn the oven on for canning.

By mid-August, I was making a half- to whole-gallon of fermented salsa per week, and we were eating it just as fast. It makes a great snack and is a tasty conversation starter when brought to backyard cookouts. Suddenly, adding fermented foods to your diet is as easy as breaking out the tortilla chips! It also makes the best topping for tacos and grilled meats. 

Below is the basic recipe. I change the proportions a little each time, based on what I have ripening in my garden or on the kitchen counter at that moment, and how much I could fit into the half-gallon jar. 

Ingredients:

  • 2-3 lbs ripe tomatoes 

  • 1 small onion

  • 1-3 cloves of garlic

  • 2-3 bell peppers

  • Hot peppers of your choice (I like my salsa more mild, so I use 1 jalapeno or 2 hungarian hot wax peppers, but the sky's the limit!)

  • Cilantro (stems included), or a mix of cilantro, pepiche, and papalo leaves

  • Salt to taste

Method:

  • Finely chop all ingredients into similar sizes and layer into a half-gallon mason jar. Add salt and taste; it should be just shy of “too salty”. Stir well (a long-handled cocktail stirrer works well), and cover loosely with the jar lid. Place jar on a plate to catch any overflow during fermentation, and leave on your kitchen counter. 

  • Shake jar (with lid tight) 2-3 times per day, loosening the lid to allow for gas to escape through the course of the day. You will start to see bubbles rising to the surface, but shaking ensures that all ingredients stay below the liquid.

  • After a day or two, taste to evaluate how the tanginess is developing. Depending on weather, it could take anywhere from 2-5 days to achieve desired levels of fermented flavor. You get to decide when you think it’s ready!

  • Eat immediately, or funnel into smaller jars and store in the fridge. It will store indefinitely, slowly building its fermented flavor, but good luck getting it to last long enough!

  • Note: If your tomatoes are really juicy, you may want to strain some of the excess liquid when transferring to storage jars. This fermented tomato juice is a refreshing drink, and makes a great addition to gazpacho or cocktails!
