EuroQuest"s beautifully crafted Fermenting Crocks (aka Fermenting Pots) are an easy, clean and safe way to make sauerkraut, pickles and other fermented vegetables. These crocks are perfect to ferment healthy and delicious vegetables through a traditional method for naturally preserving food through culturing in a salt/water brine solution. The lid fits into a specially designed gutter on the crock, creating an airtight seal that will permit gasses to escape in the fermentation process, while keeping air out. The stones are placed inside the crock to hold contents below the brine level. Made in Poland, this beautiful sauerkraut crock or pickling crock will stand the test of time. Stone included.
