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 ↓
Pudding Sauce
Ingredients
Directions
Combine 1 pint of water with a heaping tablespoon of flour in a pot to create a smooth starch.
Cook for 10 minutes, straining if necessary.
Sweeten to taste.
Pour the mixture over 1 tablespoon of butter and the juice of a lemon or vinegar for flavor.
For a richer sauce, add more butter and sugar, stirring them to a cream with the flavoring before adding the starch.

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
- Flour
- Thickens the water into a smooth, pourable sauce as its starch cooks.
- Butter
- Adds richness and a silkier mouthfeel to the finished sauce.
- Lemon juice or vinegar
- Adds acidity that brightens the sweetness and balances the flavor.
The step that matters
Cook the starch smooth before adding flavor. Flour thickens only when its starch is cooked in liquid. Adding it lumpy or undercooked leaves a pasty, raw-tasting sauce, so stir well and cook it fully before sweetening.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter, sugar):

- Lemonthe original
Fit is the average pairing score against flour, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
