Scalloped Crabs

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Remove the meat from the shells of the crabs, discarding the stomach, intestine, and soft fins, but saving the green fat and curd.

  2. Chop the hard-boiled eggs finely and grate the lemon rind.

Make the sauce

  1. In a saucepan, melt the butter and flour over medium heat until bubbling.

  2. Gradually stir in the milk and bring the sauce to a boil.

Combine and bake

  1. Season the sauce with salt, pepper, and cayenne, then add the crab meat, chopped eggs, and lemon juice.

  2. Heat the mixture together, then transfer it to scallop shells or a serving dish.

  3. Dust the tops with cracker crumbs and brown in a hot oven at 400°F (200°C).

  4. Serve immediately.

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 gives its sweet, delicate flavor.
Hard-boiled eggs
Add body and richness to the filling, giving it a softer, more substantial texture.
Butter
Adds fat and flavor and forms the base of the roux with the flour.
Flour
Thickens the milk into a smooth sauce that holds the filling together.
Milk
Forms the liquid base of the sauce, adding creaminess.
Lemon juice
Adds acidity that brightens the rich sauce and crab flavor.

The step that matters

Gradually stirring the milk into the butter and flour. Adding the liquid slowly while stirring keeps the starch dispersed, so the sauce becomes smooth instead of lumpy. The starch must then come to a boil to fully thicken.
