Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Adds richness and body, helping the icing hold together smoothly.
- Lemon juice
- Provides acidity and bright lemon flavor that balances the sweetness.
- Confectioner's sugar
- Supplies sweetness and, once dissolved in the liquid, thickens the icing.
The step that matters
Gradually beat in confectioner's sugar. Powdered sugar clumps when dumped in at once. Adding it gradually lets each portion dissolve and hydrate evenly, giving a smooth, lump-free icing.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
