Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Directions
Prepare the flour
Tie the flour tightly in a cloth and boil for four hours.
Scrape off the outer crust to reveal a dry ball inside.
Grate the dry ball as needed.
Make the sauce

Add ¼ teaspoon of coarse sea salt.
If desired, stir in the beaten egg white before serving.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Flour
- Thickens the milk as the grated starch swells and sets into a smooth, creamy sauce.
- Milk
- Forms the liquid base that the flour thickens into a smooth, creamy sauce.
The step that matters
Stir the grated flour into the boiling milk until smooth. Starch grains clump if they hit hot liquid in a mass. Mixing the flour with the milk while stirring keeps the grains separated so they swell evenly and the sauce stays smooth rather than lumpy.
