Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that gives the dessert its light, airy structure.
- Fine sugar
- Sweetens the froth and helps stabilize the beaten egg white foam.
- Lemon juice
- Adds acidity that brightens the sweetness and helps keep the foam stable.
- Currant jelly
- Adds fruity sweetness and tartness along with a glossy color to the froth.
The step that matters
Beat the mixture until it forms a stiff froth. Egg whites must be beaten enough to trap air and hold stiff peaks. Under-beaten whites stay runny and collapse, while over-beaten whites turn dry and grainy.
Swap the currant
How well each one fits the dish's main ingredients (lemon, egg, sugar):
- Orangefits better
- Vanillafits better
- Limefits better
- Currantthe original
Fit is the average pairing score against lemon, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
