Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Supplies the main flavor and, once melted and cooled, the frosting's body.
- Butter
- Adds fat that makes the frosting smooth, rich, and easier to spread.
- Confectioners' sugar
- Sweetens and thickens the mixture so it becomes a spreadable frosting.
- Hot water
- Loosens the melted chocolate and butter so they blend into a smooth liquid.
The step that matters
Judge the consistency after cooling. The mixture thickens as it cools, so sugar added while it is still warm can leave the frosting too thin. Adding sugar gradually and checking after cooling prevents a stiff or runny result.
