Fermentation Pounder

pH strips are a quick and easy way to check the acidification of your cheese and ferment.

In a lactic ferment and in cheese making beneficial microbes are underway to turn plant sugars and lactose into lactic acid.

This acidification can be measured and ensures your ferment or your cheese is on the right track.

For most cheeses timing of salting is really important; you want the fermentation to be just at the right acidity before you apply salt to slow it down.

One thing that should be in just about everyone's diet are fermented or cultured foods. Not only are they packed with flavor, but they're positively brimming with probiotics.

Those little microorganisms support your immune system and help to revive and maintain gut health. Fermented foods are also rich in B vitamins, food enzymes and key antioxidants that support healthy cells.
