Of Course, bitter melon tastes some bitter.  A lot people don’t like the bitter taste. But once you fall in love with it, you’ll like it as it is. there are seeds inside bitter melon, and you don’t want to cook it with the seeds.  To clean the seeds, I normally use a spoon to scoop all the white out of it. Then it won’t taste too bitter after cooking.
