Egg and sauce barely smell alike, yet cooks put them together in 10,895 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Hard-cooked eggs
Provide firm, sliceable body and rich flavor throughout the layers.
Flaked fish or meat
Supplies the savory protein base that gives the casserole its substance.
Buttered crumbs
Form a crisp, golden topping and absorb some moisture from the sauce.
White sauce
Binds the layers together and keeps the casserole moist as it bakes.

The step that matters

Bake until the crumbs are lightly browned. Baking long enough sets the white sauce and lightly browns the buttered crumbs through the Maillard reaction, giving a golden top and a cooked, stable interior. Stopping early leaves the sauce loose and the topping pale.
