Why it works: Crab and meat work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 448 recipes. Both carry 2,3,5-trimethylpyrazine, which smells cocoa, roasted. The science ↓
Crabs Au Gratin
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Lay the crab meat in a deep buttered dish.
Make the sauce
In a saucepan, heat the butter and flour to make a roux until smooth.
Stir in the hot stock and cook for 3 minutes.
Work in the heated cream, which should have a small amount of baking soda mixed in.
Season the sauce with salt, cayenne, and Worcestershire sauce, then pour it over the crab meat.
Bake and serve
Cover with cracker dust, sprinkle with paprika, dot with butter, and brown in the oven.

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 dish and provides its delicate seafood flavor.
- Flour
- Thickens the sauce when cooked with butter to form a roux.
- Butter
- Adds richness and flavor to the roux and the topping.
- White stock
- Provides the liquid base of the sauce, adding savory depth.
- Cream
- Adds richness and a smooth, silky texture to the sauce.
The step that matters
Stir in the hot stock and cook for 3 minutes. Adding hot stock to the roux gradually and stirring well prevents lumps. Cooking the sauce lets the flour's starch swell and thicken it fully, so it coats the crab rather than running off.
