"What should I look for when buying Belgian endive? Some are greenish, others are almost pure white. Is one preferable? Most definitely the white. Farmers grow this small, oval-shaped vegetable -- also called French endive -- in complete darkness to keep it from turning green. Supermarkets store it in boxes for the same reason. Suppliers take these precautions because when endive turns green, this already slightly bitter vegetable becomes unpleasantly so. To store endive at home, wrap it with a sheet of paper towel to absorb any moisture, then place it in a loosely tied plastic bag in the crisper compartment of the refrigerator for up to one week.
