Anyone catch the Good Eats show on crab? Beleive it or not, the best way to steam crab legs is . . . in the microwave! Hard to believe but true! I've tried this twice with outstanding results. It tastes as good as at a fancy seafood restaurant (assuming you are using fresh crab legs).
When I made mine, the grocery store had COLOSSAL king crab legs, which I had never seen before, but resulted in the biggest mouthful of succulent crab that I've ever had, it was great. This is a fool-proof, easy, impossible to mess up recipe! I love it! Enjoy!
