Stone Crab with Mustard Sauce

This classic stone crab with mustard sauce is a sophisticated seafood dish that brings a taste of coastal luxury to your dining table. The sweet, succulent meat of the crab claws provides a perfect contrast to the punchy, piquant dip. By using a blend of dry and Dijon mustards with a hint of cayenne, this recipe creates a layered heat that enhances rather than overpowers the delicate shellfish.

As a naturally dairy-free starter, this elegant dish is ideal for entertaining guests with specific dietary requirements without compromising on flavour or texture. The sauce can be prepared up to 24 hours in advance, allowing the aromatics to meld beautifully. Serve the chilled claws on a platter of crushed ice for a professional, restaurant-style presentation at home.

Ingredients for Stone Crab with Mustard Sauce

  • 3 tablespoons dry mustard

  • 1/2 teaspoons turbinado sugar (see Cooks' Note)

  • 240ml safflower or canola oil

  • 1 small clove garlic, peeled and minced

  • 1/2 small shallot, peeled and minced

  • 2 large egg yolks

  • Juice of 1 large lemon

  • 1 tablespoon Dijon mustard

  • 1 teaspoon kosher salt

  • 1/2 teaspoons cayenne pepper

How to make Stone Crab with Mustard Sauce

In a small bowl, whisk together the dry mustard, sugar, and 2 tablespoons warm water; let stand 5 minutes. In a small sauté pan over moderate heat, warm 2 tablespoons of the oil. Add the garlic and shallot and sauté, stirring occasionally, for 1 minute.

In a large bowl using a balloon whisk, whip the egg yolks for 1 minute to lighten them. Whisk in the lemon juice, Dijon mustard, salt, and cayenne pepper. Add the dry-mustard mixture, along with the garlic and shallots, and stir until blended. Gradually drizzle in the remaining 180ml plus 2 tablespoons oil, whisking to combine. Cover and chill at least 20 minutes before serving. DO AHEAD: The mustard sauce can be prepared ahead and stored, covered in the refrigerator, up to 24 hours.

Serve the mustard sauce in small bowls or ramekins, alongside the stone crab claws.
