Recipe: Fermented Kiwi Jalapeño Hot Sauce

Kiwis are some of the most fun and lively tasting fruits we know. Their bright, tropical flavor and acidity make them the perfect addition to a batch of fermented hot sauce. Coupled with jalapeños, cilantro and scallions, kiwis produces a homemade fermented hot sauce whose color is a brilliant green with a vivid flavor to match.

And since the main spicy element of this hot sauce recipe is jalapeño (which has a relatively mild heat), this is a hot sauce you can douse liberally over anything in need of a light, tropical heat. It’s one of our go-to fish taco hot sauces. It also adds a fun, delicate heat to pad thai and other noodle dishes.

Lacto-fermentation adds deep complexity to hot sauces. All the ingredients in this recipe are all specifically chosen to work together in preserving their lush tropically bright flavors. To ensure a hot sauce has a fully rounded out flavor and isn’t just a one-note spicy sauce, we often add something from the onion family to a recipe. The onion used here is scallions. Scallions are brighter in flavor than a typical yellow onion. Herb also do a ton to lift the flavor and aroma of a hot sauce. The additional of a whole lot of cilantro adds a clean freshness to the recipe that helps it shine—even after a few weeks of fermentation.

So if you’re looking for a bright, tropical, fruit-forward recipe for your next batch of homemade hot sauce, look no further. 

Want it spicier?

Replace jalapeños with a hotter pepper like Serrano chilies. Serrano will also help keep your hot sauce a verdant green.

Don’t like cilantro?

We get it. Cilantro isn’t for everybody. Try replacing it will another herb like parsley.

This was the first time I tried one of your fermentation kits…it was a blast. I followed your Jalapeno/Kiwi directions, but put in a few add-in. I added 6 small fingerling green peppers, cut down the middle, and added to each layer, a half-teaspoon of grated fresh ginger. Fermented for 15 days, and followed the instructions, but only used about 2/3rd of a cup of vinegar….the result? A not too thin, nicely balanced hot sauce, tasting of both the japaleno’s and kiwi’s, and a very slight hint of extra heat and ginger. The batch made 12 X 125 ml squeeze bottles.
