Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coffee sugar
- Dissolves into a boiled syrup that sweetens the filling and gives it body.
- Egg whites
- Whipped into a foam that gives the filling its light, airy structure.
- Raisins
- Add concentrated sweetness and a chewy texture to the filling.
- Corn starch
- Thickens and stabilizes the frosting so it holds its shape.
The step that matters
Pouring the boiling syrup over the egg whites. The hot syrup cooks the whipped egg whites into a stable, glossy foam. Pour it in a thin, steady stream while beating; a fast pour or cold whites can cause the foam to deflate or stay loose.
Swap the raisin
How well each one fits the dish's main ingredients (coffee, sugar, egg, corn):
- Vanillafits better
- Figfits about as well
- Raisinthe original
- Coconutfits about as well
Fit is the average pairing score against coffee, sugar, egg, corn. Candidates are from the same food group and used in at least 100 recipes.
