Why it works: Biscuit and mustard match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 121 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Macaroni Pie
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the ingredients
Boil the macaroni and discard the first water.
Boil the macaroni again in the milk until soft, then set aside.
Prepare a gravy with the beef, seasoned with ground pepper, salt, and soup herbs, then set aside.
Pound the cheese into fine powder.
Mix half of the powdered cheese with dry mustard, salt, and ground pepper, then set aside.
Finely crush the biscuits.
Make the filling
In a saucepan, combine the boiled macaroni with enough beef soup to cover it. Add the mixed cheese, mustard, salt, and pepper.
Cook over low heat until the gravy thickens.
Assemble and bake
Grease a baking tin with 3 oz of butter.
Pour the macaroni mixture into the tin.
Mix the remaining cheese with the crushed biscuits and sprinkle on top. Dot the remaining 1 oz of butter over the top.
Bake in the oven at 300°F (150°C) for 10 to 15 minutes until light 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 pie and absorbs the milk and gravy as it softens.
- Beef
- Provides the savoury meat gravy that moistens the macaroni and carries the seasoning.
- Milk
- Softens the macaroni further and adds moisture and richness to the filling.
- English cheese
- Adds savoury flavour and helps the filling become rich and creamy.
- Biscuits
- Crushed into crumbs, they form a crisp topping that browns in the oven.
- Butter
- Greases the tin and, dotted on top, adds fat that helps the crust brown.
The step that matters
Cooking the filling over low heat until the gravy thickens. Gentle heat lets the starch in the macaroni and gravy thicken slowly without scorching on the bottom of the pan. Rushing it with high heat can burn the base and leave the filling loose or lumpy.

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