Unlike canning or brewing beer, fermenting food is surprisingly easy and full of foods you'll actually want to eat (think, real deli-style pickles). Fermented foods have a number of advantages: They're good for your gut health and help feed the good bacteria living in us; they have a unique flavor – that umami zing; and they're extremely easy to make. All you need to get started are some jars, whey, water, salt, and some patience. Start with small batches until you're more comfortable with the process. Remember these are living foods, so after a few days you'll open the jar to see its zesty, bubbling, contents.
