Why it works: Capers and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and rich flavour, and carries the sauce's smooth body.
- Flour
- Thickens the butter and water into a smooth sauce as it heats.
- Boiling water
- Loosens the flour-butter paste into a pourable sauce.
The step that matters
Stirring in the boiling water. Flour needs continuous stirring as liquid is added over heat; otherwise it forms lumps instead of a smooth sauce, because starch grains swell unevenly when not dispersed.
“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.
