They're delicious! I've never seen one in a grocery store, but I know lots of people that grow them. They are delicious, great for you, and grow in MASSIVE numbers.
Fermented foods are the most important foods I think. I try to eat at least 3-4 different kinds of ferment each day.
Might look for some seeds while we travel to Europe at the end of summer. Thanks for sharing and fermented foods are the best!
