How To Make Fermented Salsa


Fermented Salsa is so much better than just your normal everyday salsa! First of all, it’s filled with gut loving probiotics which we all need to thrive. Second of all it’s a great way to preserve your harvest or bulk purchases of tomatoes and capsicums (Bell peppers). This is a very easy recipe to make and once you start you will be hooked!

If you are a bit hesitant about fermenting food don’t worry! It’s really quite safe and once you start you will see how easy it is to do. So let’s begin with what is fermentation?

What is lacto-fermentation?

In a nutshell lacto fermentation is when you submerge fruits or vegetables in a brine, which is a salt and water solution. Or if you salt the food and it releases its own liquid becoming submerged that way. The bacteria lactobacillus is the main player here and thrives under conditions that do not have oxygen which is why you want your food submerged. It breaks down the sugar in the food and turns it into lactic acid which gives the food it’s delicious tangy flavour. That’s why you don’t have naturally sweet, fermented foods the sugar gets devoured first!

Bad bacteria don’t thrive very well under salty anaerobic (no oxygen) conditions which is why fermented food isn’t generally pretty safe to eat. The good bacteria take over before the bad ones can. You will clearly be able to smell if the food is off. If it has a horrible smell don’t eat it! Properly fermented food might have a strong tangy kind of smell but not a rotten smell. You can always do your research to find out more but it’s pretty safe to make. Fermentation has been around for thousands of years to store food and make it easier to digest.

Onion (white or red)

Lemon or lime juiced

You do not need all the tools I will list. I will let you know what you must have and what you can live without. The extra things I list I personally like now that I ferment regularly! So, let’s first start with what you need!

Knife- make sure its sharp remember more accidents happen with blunt knives than sharp ones!

cutting board

2 litre mason jar with a lid

bowl for mixing

These are things you do not need to have but are handy!

Food processor– I use this all the time in my kitchen for chopping ingredients and making butter! I do like this brand and it even has a blender attachment so it’s multifunctional!

Weights– These are handy if you do a bit of fermenting as they keep all your ingredients underneath the brine.

Fermentation lids– I really like these as you don’t have to worry about constantly burping your jars. These lids allow the pressure build up to be released naturally! Or of course you can just remember to burp your jars every 12 hours or so to let out some of that built up pressure!

How To Make Fermented Salsa

Mixing up ingredients for fermented salsa.

Making fermented salsa is super easy!

  1. Either chop up all your ingredients into bite size pieces by hand or rough chop and throw them into your food processor and pulse a few times.
  2. Afterward mix in all the spices and lemon juice.
  3. Once it’s all mixed nicely together give it a little taste and see if you like it. If it’s tasty start placing the mixture into your clean glass mason jar and put the weight in if you have it. If not it’s fine just place the lid on top! You do not need to create a separate brine for this recipe. The salt will bring out enough liquid from the tomatoes and other vegetables that it should be completely submerged in your jar.
  4. Place the lid on and let it sit away from direct sunlight for 2-3 days on the counter. Depending on how hot it is will determine if it’s ready in 2 or 3 days so give it a taste after 48 hours and see if you like it. You should see bubbles forming in your jar this shows that the fermentation is happening!
  5. Remember to burp your jars every 12 hours or so to let out the built in pressure. Just open the lid a little and then close it back up again. I also sometimes place a bowl under the jar as it can leak out extra liquid!
  6. Once you like the taste of your salsa place it into the fridge. Will keep for several months in the fridge and enjoy whenever you want salsa!

How To Store Salsa

Storing fermented salsa is very easy you can place it into the fridge with a tight lid. It should last several months in the fridge no problems. Just give it a smell and little taste if you are worried but honestly you will most likely eat it up before then.

You can also freeze it. Just remember when it comes out of the freezer it might be a bit on the mushier side but it’s still very tasty you can even add it as a pasta sauce replacement! It can keep in the freezer for quite a while if stored well 6 months up to even a year!
