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 ↓

Ingredients
Directions
Make the syrup and meringue
Boil the sugar and water until it ropes.
Pour the syrup gradually over the beaten egg whites and beat until stiff.
Make the chocolate base
Melt the chocolate, then add 1 cup of sugar and ¼ cup of milk.
Stir and cook until a little forms a soft ball in cold water.
Finish the frosting

Add the syrup to the egg mixture in a fine stream while beating constantly.
Stir in 1 teaspoon of vanilla.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to foam, they give the frosting its light, airy structure.
- Granulated sugar
- Dissolved into syrup, it sweetens the frosting and helps it set glossy.
- Chocolate
- Melted into the base, it supplies the chocolate flavour and richness.
- Egg yolk
- Adds richness and fat, giving the frosting a smoother, creamier body.
- Milk
- Adds moisture and softness to the chocolate base.
The step that matters
Add the syrup in a fine stream while beating. Hot syrup poured slowly while beating cooks the egg proteins gently and blends evenly. Pouring it in quickly can cause lumps or scramble the eggs, and the frosting may not become smooth and stable.
