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.
Drain the macaroni, rinse in cold water, and cut into 1-inch lengths.
Make the sauce
In a saucepan, make a roux by stirring the flour in hot butter until smooth.
Gradually add the scalding milk and baking soda to prevent curdling.
Add the macaroni, minced ham, dry mustard, and cayenne to the roux.
Stir in the beaten egg.
Bake and serve
Pour the mixture into a buttered baking dish.
Top with cracker crumbs and grated cheese.
Bake covered in a 400°F (200°C) oven for 30 minutes.
Uncover and brown the top.

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 firm, chewy body once baked.
- Flour
- Thickens the butter and milk into a smooth sauce that holds the casserole together.
- Milk
- Forms the liquid base of the sauce, adding moisture and creaminess.
- Egg
- Sets during baking, binding the sauce and pasta into a sliceable casserole.
- Ham
- Adds savory, salty meat flavor throughout the casserole.
- Grated cheese
- Melts and browns on top, adding richness and a golden crust.
The step that matters
Gradually add the scalding milk and baking soda. Adding the hot milk slowly to the roux keeps the flour evenly dispersed so the sauce stays smooth instead of lumpy. Adding it gradually also helps prevent the egg-free sauce from curdling when the alkaline baking soda is introduced.
Swap the mustard
How well each one fits the dish's main ingredients (flour, butter, milk, ham, pepper, egg, cheese):

Fit is the average pairing score against flour, butter, milk, ham, pepper, egg, cheese. Candidates are from the same food group and used in at least 100 recipes.
