Parboiling bitter melon: Bring a large pot of water to a boil. Cut the ends off the bitter melon and cut in half lengthwise (do not peel). Remove the seeds and white pith from the middle of the melon with a small spoon. Cut the melon diagonally into thin, 1/4-inch slices. Place the sliced bitter melon in the boiling water and parboil until it is just tender (2 - 3 minutes). Drain.
