Definitely made clams in white wine before but never champagne or bubbly….solid 10/10 tho. Bathe your clams in salt water and rinse. In a pot, fry some shallots and garlic then add the clams and a good pour of bubbly. Throw in some parsley and chili flakes and cover until they’ve all fully opened. If any don’t open after a few minutes, throw them out. Enjoy with some toasted bread.
