Why Do I Need To Start Pickling?

First off, it's tasty and easy! But fermenting your foods also has multiple health and flavor benefits including making vitamins and minerals more available to your body and providing a powerful punch of probiotics and enzymes. It's a great way to preserve food while still keeping it raw and full of nutrients. Lactobacillus, the bacteria that produce your sour flavor, only thrive in an oxygen-free environment, while most molds and bad microorganisms require oxygen to survive. This lid provides the correct Lacto-fermenting environment for maximum growth of good bacteria while minimizing undesirable bacterial growth.

How Do I Get Started?

It's really very simple! The correct ratio of salt and an oxygen-free environment keep bad bacteria and mold in check until Lactobacillus, also known as LABs or “good bacteria,” can populate the ferment. LABs produce lactic acid for that sour pickle flavor and lactic acid will further inhibit any bad microorganisms from growing. LABs like a moist, salty, oxygen-free, room temperature and dark environment. They are naturally present in vegetables and will proliferate quickly if given their desired conditions.
