Why it works: Flour and capers match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 1,024 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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
- Mutton
- Long simmering turns the tough meat tender and moist.
- Flour
- Thickens the sauce and gives it body.
- Butter
- Adds richness and smooth texture to the sauce.
- Pickled capers
- Add a sharp, acidic bite that cuts through the rich butter.
The step that matters
Stir the flour and butter sauce over heat. Stirring while the mutton water is added and heated keeps the flour evenly dispersed, preventing lumps and letting the starch thicken the sauce smoothly.
“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.
