Keep Food Protected Cover goes right on top of your crock to keep food safe while fermenting. Fits the 5-gallon numbered stoneware crock. Available in brown. About 15"OD, 9-1/2 lb. USA made in Ohio. Crock is sold separately. Helpful Hints for Fermenting: Make sure to check your sauerkraut once a week. Skim off any scum on top. Remember, the better quality ingredients you use, the better results you'll have. Wooden boards will naturally swell during fermenting. Make sure the board you use fits properly in the crock. If it is too snug, it may get stuck.
