They were always done like this! Baked scallops. Original Galician recipe.

What ingredients do I need for this recipe?
Scallops and their shell.
Onions.
White wine.
Olive oil and salt.
With these ingredients, you can now make the recipe. I added a little crushed tomato, garlic and parsley, just like my mother-in-law does.
I hope you like baked scallops, it is a symbol of parties and celebrations.
