Chop all the tomatoes, onions, chillies, garlic, capsicum, and coriander into small pieces.
Mix with Spices
In a large mixing bowl, add the chopped vegetables along with oregano, chilli powder, and lemon juice.
Mix thoroughly until everything is well combined.
Pack into the Jar
Transfer the mixture into a clean 1-litre fermentation jar.
Pack it down tightly to remove air pockets.
Add Weights
Place the glass weights on top and press down so the veggies are submerged in their juices.
Make sure everything stays under the liquid.
Seal & Ferment
Close the jar with the lid and attach the airlock.
Fill the airlock with water.
Fermentation Process
Leave the jar at room temperature to ferment for 3–4 days.
Taste daily to check the flavor.
Store
Once the salsa reaches the desired tanginess, replace the airlock with a storage lid and refrigerate.
