Recipe for oysters in foil with butter?

I had oysters w/ enoki mushrooms & butter baked in foil at a japanese restaurant and I'm looking to replicate the recipe at home.Does anybody have any recipes they like? I've been searching the internet but haven't come across anything specifically.Otherwise I'm just going to throw the shucked oysters into a foil bag with a tablespoon of butter and some soy sauce and sake. Maybe 350F for 7 minutes? via /r/Cooking https://ift.tt/2KnOYCt
