Etienne's Soft-Shell Crab with Red Chili Beurre Blanc

Etienne’s soft-shell crab with red chili beurre blanc is the kind of restaurant-style plate that proves how impressive a fifteen-minute dish can be when the crab is in season. Soft-shell crabs (blue crabs caught in their brief post-molt window when the new shell hasn’t yet hardened) get a triple-coat treatment: a flour-salt-pepper dust, a dip in beaten egg, then a coating of mixed bread crumbs, grated Parmesan, and cornmeal that delivers a crackling golden crust when pan-fried in peanut oil and butter.

The sauce is a classic French beurre blanc with Southwestern attitude. Shallots cook gently in clarified butter, then a splash of lime juice, white wine, and vermouth reduces almost to a glaze. Heavy cream goes in next as an emulsifier, then twelve ounces of cold butter cubes whisk in piece by piece off the heat to build the silky, glossy sauce. Spoon onto plates, perch the crisp crabs on top, scatter with parsley.

Pro Tips

• Buy live or freshly killed soft-shell crabs from a fish market that knows what they’re doing. Cleaning involves removing the gills, mouth, and apron. Most fishmongers will do it for you on request.
• Don’t overcrowd the pan as the directions warn. Crabs need space to crisp; crowded crabs steam and the crust turns soggy.
• Whisk the cold butter into the beurre blanc off the heat. Butter added over high heat breaks the emulsion and you get a greasy mess instead of a glossy sauce.
• Serve immediately. Beurre blanc holds for about ten minutes off heat in a warm spot. Longer than that and it separates.

Variations

• Add a teaspoon of red chili flakes or chopped chipotle to the beurre blanc for the actual ‘red chili’ the dish title promises (the original ingredients seem to be missing the chile).
• Sub fresh lemon for the lime in the sauce for a more classic French profile.
• Use Old Bay seasoning in the breading for a more Maryland-style crab cake feel.
