Is this a self-creation? If so, would you mind sharing the recipe after the contest? I understand if not.
That's hitting on about three or four of my buttons (scallops, shrooms, lemongrass, sake...)
It's mine and I've no problem sharing. I've made this several times and the recipe always varies a little based on what I have on hand. However, the principals are the same. Marinate the scallops, grill the scallops, combine ingredients and cook the shrooms.
For the marinade (this, BTW, is unreal for Salmon or even better Tuna). For baby scallops I just put them in fridge about an hour. The others overnight as it works as a cure.
1 cup soy sauce
¼ cup sake
¾ cup packed brown sugar
8 slices peeled fresh ginger
1 tablespoon chopped garlic
2 teaspoons kosher salt
Grill or cook some onion, peppers in a skillet 1/2 stick butter until done. Add the baby scallops, some of the marinade, fresh ginger, chopped lemongrass (or lemon grass paste) and whatever herbs you want prefer. Cook for about 3 minutes.
Hollow out large mushroom caps, bush with olive oil, salt, pepper, and fill with the mixture after straining the liquids. I personally eat low carb...so i don't mix with breadcrumbs or rice. You can do this now if you prefer...I lightly sprinkle breadcrumbs on top.
Soak your planks for at least an hour, add the shrooms and cook until done. About 10-15 minutes then add cheese. I use Parmesan cheese.
Pretty much it. Virtually everything can be substituted (i.e Mexican style with shrimp, tequila, lime, cumin etc).
