Ingredients

Crab Butter Sauce (Base):

  • ¼ cup butter (½ stick)
  • ½ lemon, juiced
  • small pinch sea salt (optional) Omit if using salted butter or if serving along with heavily seasoned crab.

Garlic Butter:

  • 2 cloves garlic, finely diced

Spicy Butter:

  • 1 teaspoon red chili flakes

Lemon Butter:

  • zest from one lemon

Instructions

  • Melt the butter over medium-low heat.
    Allow the butter to melt but not brown.
    Add Butter To Saucepan
  • As soon as the butter melts, add any extra seasoning if desired (garlic, red pepper or lemon zest).
    Continue heating 1-2 minutes, or until the seasonings become fragrant.
    Stir in the lemon juice. Serve warm along with crab legs.
    Season the Butter

Notes

Make Ahead:  Butter can be refrigerated for up to 5 days or frozen for up to 6 months. 
Freezing Tips: If freezing, you may want to portion the butter into smaller amounts by freezing in silicone molds (such as a silicone ice cube tray).  Once frozen, transfer the frozen butter into an air-tight container.
