Boleslawiec Polish Pottery 20 Liter / 84 Cups Fermenting Crock Pot - PRESSING STONES INCLUDED Dimensions: Capacity: 20 Liter / 84 Cups, Height: 17 Inch Handcrafted in Poland from dense, glazed stoneware for excellent temperature stability, which significantly improves the flavor of the finished food. Just add vegetables and salt, top with weights (not included) and cover with lid to start the fermentation process. As fermentation begins, naturally occurring carbon dioxide drives the air out of the pot, creating an oxygen-free environment inside. Also ideal for making kimchi and pickled cucumbers, or for curing olives.
