Clean your work surface thoroughly and gather your materials. You'll need a mason jar with lid, kitchen scale, knife and peeler for this ferment.
Wash, peel and dice your mangos.
Weigh your jar without anything in it, then zero out your scale with the jar still on it.
Add your mangos to the jar and jot down weight.
Zero out the scale with the jar of mangos on it.
Add 2% sea salt*
Pour filtered water (just to top of fruit).
Add your weight and make sure all the mangos are submerged. I just used a bag of mango cores as my weight.
lightly fit your lid on the jar.
Allow to sit at room temperature for about 48-72 hours checking every 24 hours.
You'll know your fermented mangos are done when they have a pleasently salty taste and may start to taste fizzy as a result of the lactic acid fermentation.
Remove the weight, tightly fit your lid and store in the refrigerator.
