You sure can. I try to be careful that my butter sauce complements the delicate flavor of the crab meat and doesn't compete with it. But that's a personal preference. If you love garlic, add a couple of minced garlic cloves to the butter sauce and don't remove them when serving. Looking for an Asian flair, add a tablespoon of ginger scallion sauce to the butter sauce, or make this miso butter as your dipping sauce. If you're hoping for that crab boil flair, add a teaspoon of Old Bay seasoning to the butter sauce. Taste and adjust before serving.
