Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Lemon Sauce
Ingredients
Directions
Make the sauce
In a saucepan, combine white sugar, brown sugar, milk, and butter.
Boil the mixture until it reaches a candy-like consistency.
Just before removing from heat, stir in lemon juice, vanilla extract, citron, raisins, and candied cherries.
Serve
Use the sauce between layers of white cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Sweetens the sauce and, with brown sugar, cooks down to a candy-like thickness.
- Brown sugar
- Adds sweetness and a deeper, molasses-like flavour and helps the sauce set firm.
- Milk
- Provides the liquid base that the sugars and butter cook into a thick sauce.
- Butter
- Adds fat for smooth richness and a glossy texture.
- Citron
- Adds chewy texture and candied fruit flavour throughout the sauce.
The step that matters
Boiling to candy-like consistency. Sugar concentration rises as water evaporates, so the sauce can turn grainy or stay too thin if boiled too little or too long. Watching for the candy-like stage controls final texture.
