Now that we are just on the verge of tomato and pepper season, I wanted to share this recipe for cultured salsa. Fermenting salsa is an easy way to make it last longer without canning and it adds a probiotic boost.
We eat and drink a lot of fermented foods, from water kefir soda to sauerkraut, and fermented salsa is definitely one of the easiest ways to get the benefits of fermented foods in your diet.
If done properly, fermented salsa will last months in the fridge or in cold storage and get more probiotics with age. Plus it tastes delicious with some homemade tortilla chips!

Notes
A Fast and Easy Tip
If you don’t have the time or ingredients to make your own salsa, you can get the benefits of fermented salsa by fermenting store bought salsa as well. If possible, use the fresh made salsas in the refrigerated section, but you can ferment canned versions also.
Is your kitchen a small scale chemistry lab like mine? Do jars of foods in various stages of fermentation clutter your counter as they do mine? What’s your favorite?
Hi
Can i omit the whey from the recipe
Not really, it’s what causes the salsa to ferment and have probiotics. You could leave it out, but then it would be a regular non-fermented salsa and it would need to be put in the fridge right away (skip the leaving it out to ferment step).
We have made this recipe half a dozen times and when it turns out it is the best thing ever. We literally go through it in a week. But half the times it clearly over ferments – I can’t tell what I am doing different. Maybe that it is summer? Maybe I should ferment it in the fridge instead? Any ideas? Thanks!
It is very temperature dependent so in warmer months, keeping it in a cooler place or even the fridge can help a lot!
I live in a place where the room temperature can rise to 40 degrees celcius during the day. Would it be safe to leave the salsa at room temperature for 2 days? Thanks
I made this salsa today! I puréed it then stirred in the whey. It has separated. Should I stir it up? I am wondering, like a few of the others, how to tell if it has fermented. By the way, it is delicious!!!
Can I use powdered probiotics instead of whey?
