Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
White Frosting
Ingredients
Directions
Make the syrup
Combine sugar and water in a saucepan and stir to prevent sticking.
Heat to boiling and boil without stirring until syrup threads from a spoon.
To prevent sugar granules, dip hands in cold water and then into the hot syrup, repeating several times.
Finish the frosting
Gradually pour syrup onto the beaten egg white while constantly beating.
Continue beating until the frosting reaches a spreadable consistency.
Add vanilla extract and spread on cake.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the syrup that sets into a smooth, sweet frosting structure.
- Egg white
- Whipped into a foam that gives the frosting its light, airy body.
- Water
- Dissolves the sugar so it can be boiled into a syrup.
The step that matters
Pouring the syrup onto the egg white. The syrup must be hot and poured slowly in a thin stream while beating constantly. Pouring too fast or letting it cool can deflate the foam or leave the frosting grainy and uneven.
