Completely cover the frozen crab legs with water, so you may need a large roaster depending on their size. Add 2 inches of water to a roaster or fill a stock pot. Add crab legs to gently boiling water, cover with a lid or tin foil and cook for 5 minutes until heated through. Don’t add any salt to the water.

Cut tender part of leg with scissors. Serve with clarified butter in Butter Warmers and sliced lemons.
