Fermented Hot Sauce Recipe

Get ready to set your meals on fire with this lacto-fermented hot sauce recipe!

Did you know that all hot sauces are usually fermentations? They are actually lactic fermentations (also called lacto-fermentations), like sauerkraut, kimchi, or pickles.

Lacto-fermented sauces are not only very easy to make, but they are absolutely delicious.

Fermenting chilies with aromatics allows the flavours to blend and become more complex. Fermentation also adds a pleasant acidity, far less aggressive than vinegar-based hot sauces.

In addition to being delectable, this hot sauce is all-purpose and will quickly replace your favourite brand of sriracha.


Choosing the Chilies

In this recipe, we use red jalapeños because they have a nice colour and are easy to find in grocery stores.

Depending on your tolerance to spiciness, substitute them with any chili pepper: Thai, Serrano, habanero, scorpions… or even sweet peppers. It’s your sauce and you can do what you want!

This recipe uses fresh chilies. If you want to use frozen or dried chilies, add a source of lactic acid bacteria to get the fermentation going.

Remove the green stems from the chilies before putting them in the jars. You can also empty the inside and remove the seeds so that the final product is less spicy.


Choosing Aromatics

Three classic ingredients for hot sauces are used here: carrots, onions, and garlic.

By fermenting them with the chilies, they add a lot of roundness and complexity to the sauce.

Depending on what you like (or what you have in your fridge), feel free to try other aromatics! This recipe provides a basic sauce that can be easily customized. Add ginger, lemongrass, pomegranate molasses, pineapple, Za’atar spices…

Well, maybe not all at once!

You can also easily double or triple the recipe. A homemade hot sauce is a great gift, and it keeps for a long time.
