Why it works: Butter and flour 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 ↓
Drawn Butter Sauce
Ingredients
Directions
Make the roux
In a stew‑pan, melt 2 tablespoons of butter over medium heat until it bubbles.
Sprinkle in the flour and stir well with a whisk until the flour is cooked but not browned.
Finish the sauce
Gradually mix in the ½ pint of water and remove from heat.
Pass the mixture through a colander.
Stir in the remaining 1 ounce of butter until melted and well combined.

Butter and flour 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
- Butter
- Adds richness and fat, carrying flavour through the sauce.
- Flour
- Thickens the sauce as its starch swells when cooked in the melted butter.
The step that matters
Cook the flour without browning it. Flour must cook in the hot butter long enough to lose its raw, floury taste and to thicken the liquid properly. If it browns, the sauce takes on a darker colour and a toasted, bitter flavour, so keep the heat moderate and stir constantly.
“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.
