Dressed Crab

Ingredients

Directions

Cook the crab

  1. Boil the crab in slightly salted water for 30-40 minutes, depending on its size.

  2. Remove the crab from the water and let it cool.

  3. Remove the large and small claws, crack the large claw shells, and extract the meat.

  4. Set aside about 2 tablespoons of the crab meat for later use.

Make the dressing

  1. Combine the creamy part from the body and claws in a bowl.

  2. Add anchovy essence, French tarragon vinegar, chili sauce, salad oil, mixed English mustard, French mustard, cayenne pepper, coarse sea salt, stiffly whipped cream, lemon juice, castor sugar, fresh tarragon, and fresh chervil to the bowl.

  3. Mix everything together with a wooden spoon.

Fill and serve

  1. Fill the cleaned crab shell with the mixture, piling it in the center.

  2. Sprinkle the reserved crab meat over the top.

  3. Arrange the small claws around the filled crab shell and garnish with parsley.

  4. Serve for breakfast, luncheon, or as a second course.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Crab meat
Forms the main body of the filling and provides its rich, sweet flavor.
Stiffly whipped cream
Adds lightness and a smooth, creamy texture to the dressing.
Salad oil
Adds fat that gives the dressing a smooth, emulsified body.
Anchovy essence
Adds a savory, salty depth to the dressing.
French tarragon vinegar
Adds acidity that brightens the rich crab and balances the fat.
Mixed english mustard
Adds sharp heat and pungency that cuts through the richness.

The step that matters

Mix the dressing gently into the crab. Overmixing or letting the whipped cream deflate can make the filling dense and loose. Mixing just until combined keeps the dressing light while the oil and cream stay evenly distributed.

Swap the tarragon

How well each one fits the dish's main ingredients (crab, anchovy, vinegar, sauce, mustard, pepper, cream):

  1. Capersfits about as well
  2. Tarragonthe original
  3. Garlicfits less well
  4. Celeryfits less well

Fit is the average pairing score against crab, anchovy, vinegar, sauce, mustard, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
