1In a large bowl, combine the chopped tomatoes, onion, garlic, jalapeño, and cilantro.
Add the sea salt and lime juice to the mixture.
Stir the ingredients thoroughly to ensure even distribution of the salt and lime juice.
Transfer the mixture to a clean glass jar, pressing down to remove any air pockets.
Cover the jar with a lid or a cloth secured with a rubber band.
Allow the salsa to ferment at room temperature for 2-3 days, checking daily for taste and to release any built-up gases.
Once the desired flavor is achieved, refrigerate the salsa to slow down the fermentation process.
