Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Stewed Prawns
Ingredients
Directions
Make the sauce
In a saucepan, combine the flour and 3 oz of butter without heating.
Add pepper, salt, and warm water, then stir for 2 minutes over low heat.
Remove from heat and mix in the lemon juice and 6 oz of butter until melted.
If the sauce is too thick, add water to reach the desired consistency and keep warm without boiling.
Add the prawns
Add the skinned prawns to the sauce and stir to coat.

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 butter and liquid into a smooth, stable sauce.
- Butter
- Adds richness and a silky texture as it melts into the sauce.
- Lemon juice
- Adds acidity that brightens the buttery sauce.
- Prawns
- Provide the main protein and are coated by the sauce.
The step that matters
Keep the sauce warm without boiling. Boiling can cause the butter emulsion to break and turn greasy, and it can make the sauce thicken unevenly. Gentle heat keeps it smooth and glossy.
