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
- Sweetbread
- Forms the main body of the dish, becoming tender as it simmers in the sauce.
- Flour
- Thickens the butter and liquid into a smooth, body-giving sauce.
- Butter
- Carries flavor and enriches the sauce while the flour cooks into it.
- Milk
- Adds creaminess and richness to the sauce, softening its flavor.
- White stock
- Supplies the savory liquid base that the sauce is built on.
The step that matters
Let it boil. Bring the sauce to a boil after adding the liquids so the flour fully thickens it; milk can scorch or separate if held too hot on the base, so keep the heat controlled while stirring.
Swap the parsley
How well each one fits the dish's main ingredients (flour, milk, lemon, pepper, butter):
- Parsleythe original
- Cardamomfits about as well
- Cinnamonfits about as well
- Thymefits less well
Fit is the average pairing score against flour, milk, lemon, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
