How to eliminate bitterness from a recipe

Need more info!! Also try honey or corn syrup depending on whatever you're making. Happy Thanksgiving!!

I'll second ChefOno on the sugar, and also add that fat can tame bitterness in a recipe too: butter, cream, oil, bacon, lard, whatever works with whatever you're cooking.

Not knowing what's causing the bitterness, all I can say is "add sugar".
