Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Crab Scalloped
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove the meat from the claws and body of the crabs, discarding the unwholesome part near the head.
Make the filling
Mix the crab meat with breadcrumbs, salt, pepper, mustard, and vinegar.
Add white sauce until the mixture reaches the right consistency.
Bake
Transfer the mixture into buttered scallop shells and sprinkle with breadcrumbs.
Top with small pieces of butter.
Bake in a moderate oven at 350°F (175°C) for about 20 minutes until browned.

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 gives the dish its flavor.
- White sauce
- Binds the mixture and adds moisture so it holds together in the shells.
- Breadcrumbs
- Absorb liquid and give the filling body, and the topping browns in the oven.
- Vinegar
- Adds a touch of acidity that brightens the rich crab and sauce.
The step that matters
Bake until browned. Baking long enough sets the white sauce and browns the breadcrumb topping. Underbaking leaves the filling loose and pale, while overbaking can dry the crab meat.
Swap the mustard
How well each one fits the dish's main ingredients (crab, sauce, vinegar, pepper, butter):
- Capsicumfits about as well
- Mustardthe original
- Onionfits less well
- Horseradishfits less well
Fit is the average pairing score against crab, sauce, vinegar, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
