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.
Combine
Cut the butter and cheese into small pieces.
Place the pieces in a large bowl with the bread crumbs.
Pour the scalding milk over the mixture.
Add the beaten egg yolks and a pinch of salt, then mix well.
Melt and thicken
Cover the mixture.
Place the covered mixture on the back of the stove.
Stir occasionally until dissolved.
Bake and serve
Fold in the beaten egg whites until stiff.
Pour into a buttered pie plate.
Bake at 400°F (200°C) for about 20 minutes.
Serve immediately after removing from the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the sauce, and whites folded in lighten it and help it set and rise.
- Cheese
- Provides fat and rich flavor, and melts into a smooth, creamy sauce.
- Butter
- Adds fat and richness, helping the cheese melt smoothly and giving a tender texture.
- Milk
- Provides the liquid base that melts the cheese and keeps the mixture moist and smooth.
- Bread crumbs
- Add body to the mixture and help it hold together as it thickens.
The step that matters
Fold in the beaten egg whites until stiff. Folding gently keeps the air in the whites, which lightens the sauce and helps it puff and set in the oven. Overmixing deflates the foam and leaves a dense result.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
