Why it works: Tarragon and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 901 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓
Devilled Crab
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
In a bowl, mix the white sauce with anchovy, tarragon vinegar, salt, cayenne, black pepper, and mixed mustard.
Gently fold in the meat from the body and claws of the crab.
Bake and serve
Place the crab mixture back into the crab shell in a pie dish.
Sprinkle browned breadcrumbs on top and dot with small pieces of butter.
Heat through in the oven at 350°F (175°C) until warmed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab
- Forms the main body of the dish and provides its flavour and texture.
- White sauce
- Binds the crab meat together and keeps the filling moist.
- Anchovy
- Adds savory depth and salty umami to the filling.
- Tarragon vinegar
- Adds acidity that brightens the rich crab and sauce.
- Butter
- Adds fat and richness and helps the top brown as it melts.
- Browned breadcrumbs
- Forms a crisp, golden topping over the filling.
The step that matters
Folding in the crab meat. Folding gently keeps the lumps of crab meat intact, so the filling stays tender and textured rather than turning mushy and pasty.
Swap the tarragon
How well each one fits the dish's main ingredients (crab, sauce, anchovy, vinegar, pepper, mustard, butter):
- Capersfits better
- Tarragonthe original
- Parsleyfits less well
- Garlicfits less well
Fit is the average pairing score against crab, sauce, anchovy, vinegar, pepper, mustard, butter. Candidates are from the same food group and used in at least 100 recipes.
