Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Boiled Macaroni
Ingredients
Directions
Cook the macaroni
Fill a 3-quart kettle with boiling water and add salt.
Hold the macaroni in a bunch over the kettle, with the ends in the boiling water.
As the macaroni softens, gradually introduce it into the boiling water to preserve its length.
Boil rapidly for 25 minutes until perfectly tender.
Drain the macaroni in a colander.
Make the sauce
In the kettle, add 1 pint of fresh boiling water, salt, and pepper.
Rub together the flour and butter until smooth.
Blend the flour and butter mixture with the boiling water and stir until perfectly smooth.
Add the macaroni to the sauce.
Boil for 3 minutes.
Serve
Serve in a deep dish.
Serve grated cheese separately, or break the macaroni into convenient lengths if preferred.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 dish and becomes tender through boiling.
- Flour
- Thickens the boiling water into a smooth sauce when blended with butter.
- Butter
- Adds richness and helps the flour blend smoothly into the sauce.
The step that matters
Blend the flour and butter mixture with the boiling water. Adding the flour and butter paste to boiling water while stirring disperses the starch evenly. Stirring until smooth prevents lumps, because starch clumps when it hits hot liquid without being separated first.
“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.
