Why it works: Lemon and pepper 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 ↓
Lemon Sauce
Ingredients
Directions
Make the sauce
Melt the margarine in a pan.
Add the flour and blend together without browning.
Heat the milk and water (or fish stock) and add to the flour mixture, stirring quickly.
Stir until it boils, then boil for three minutes.
Add seasoning and the juice of half a lemon.
Serve
Use some sauce to mix with the fish and serve the remainder with the pie.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Margarine
- Melts to form the fat base that the flour is cooked into.
- Flour
- Thickens the sauce when cooked in fat and combined with liquid.
- Milk
- Adds body and creaminess to the sauce as the liquid base.
- Lemon juice
- Adds acidity that brightens the flavour of the sauce.
The step that matters
Adding the hot liquid to the flour mixture. Stirring quickly while pouring the liquid in helps the flour disperse evenly, so the sauce thickens smoothly without lumps.
“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.
