Why it works: Vanilla and milk 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetened vanilla chocolate
- Provides the chocolate flavor and fat that give the frosting its richness and body.
- Milk
- Adds moisture and creaminess, helping the chocolate melt into a smooth, spreadable mixture.
- Sugar
- Adds sweetness and helps give the frosting a smooth, glossy texture as it sets.
- Egg
- Enriches the frosting and helps it thicken slightly as it cools.
The step that matters
Stir in the egg once the mixture is half cooled. If the mixture is still very hot, the egg can scramble into lumps instead of blending smoothly. Waiting until it has cooled partway lets the egg mix in evenly and thicken gently.
