National Bitter Melon Council

Selection
Select firm, unblemished melons that are from 5 to 12 inches in length. Choose melons that are still green for a more bitter flavor and a yellow-orange melon for a milder taste. Bitter Melons are available fresh from April to September in most Asian markets and can occasionally be found in larger supermarkets. Some markets are beginning to carry bitter melons year round. They may also be purchased canned, dried or as a tea, and in powdered form.

Storage
Store Bitter Melon loose in a paper or plastic bag in the refrigerator for 3 to 5 days. Slice the Bitter Melon immediately before use.
