Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Macaroni and Ham
Ingredients
Directions
The book says “a steady oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the macaroni
Boil the macaroni in salted water until tender, then drain and rinse in cold water.
Cut the drained macaroni into 1-inch lengths.
Make the sauce
In a saucepan, make a roux by stirring the flour smooth in the hot butter over medium heat.
Thin the roux with the scalding milk and add the baking soda to prevent curdling.
Stir in the macaroni, minced ham, dry mustard, and cayenne pepper.
Finally, mix in the beaten egg.
Bake and serve
Pour the mixture into a buttered baking dish.
Sprinkle cracker crumbs and grated cheese on top.
Cover the dish and bake in a 400°F (200°C) oven for 30 minutes.
Uncover and brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the casserole and gives it a tender, starchy body.
- Flour
- Thickens the butter and milk into a smooth roux that binds the casserole.
- Milk
- Forms the liquid base of the sauce, which thickens as it is heated.
- Egg
- Sets during baking, helping the casserole hold together when cut.
- Ham
- Adds savory, meaty flavor throughout the casserole.
- Baking soda
- Helps prevent the milk sauce from curdling when it is combined with the roux.
The step that matters
Thin the roux with the scalding milk. Adding cold milk to a hot roux can make lumps, and the sauce needs the milk hot to thicken smoothly. Adding the baking soda at this point helps prevent curdling.
