This Cajun Garlic Butter Seafood Boil sauce is the glossy, garlicky pool you keep going back to at the bottom of the bag, and it comes together in one saucepan in about fifteen minutes. It starts with two sticks of good butter melted low and slow, then builds with a lot of garlic, our salt-free seafood boil seasoning, fresh lemon, Louisiana hot sauce, and a splash of amber beer for malty depth. The salt-free blend keeps you in full control, so you season to taste instead of guessing. Pour it over crab legs, dunk shrimp, toss it with pasta, or brush it onto warm bread.
