Why it works: Lemon and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Lemon Sauce
Ingredients
Directions
Make the sauce
Boil the hot water and sugar for five minutes.
Add the cornstarch mixed with a little cold water.
Cook for eight to ten minutes, stirring often.
Add the lemon rind, juice, and butter.
Stir until the butter is melted.
Serve
Serve immediately.
If the sauce becomes too thick, add more hot water to reach the desired consistency.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornstarch
- Thickens the sauce as it cooks with the liquid.
- Sugar
- Adds sweetness and helps balance the tart lemon.
- Butter
- Adds richness and a smooth, glossy finish.
- Lemon juice
- Adds acidity and bright lemon flavour.
The step that matters
Adding the cornstarch. Cornstarch must be mixed with cold water before it goes into hot liquid, otherwise it clumps. Starch granules swell and thicken the sauce only once the mixture is hot and kept stirred while it cooks.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter):
- Vanillafits better

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