Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Eggs
- Egg whites whip into a stiff foam that forms the meringue topping.
- Flour
- Starch thickens the pineapple and lemon mixture as it cooks.
- Cream of tartar
- Stabilizes the whipped egg whites so the meringue holds its shape.
- Sugar
- Sweetens the filling and helps the meringue become stable and glossy.
- Lemons
- Provide acidity and aroma from the juice and zest.
The step that matters
Cook the filling until thick. Flour thickens only when the mixture is heated enough for its starch to swell. Undercooked filling stays runny and can make the pie soggy or hard to slice once set.
Swap the pineapple
How well each one fits the dish's main ingredients (lemon, sugar, flour, egg, cream):
- Raisinfits better
- Vanillafits better
- Raspberryfits better
- Pineapplethe original
Fit is the average pairing score against lemon, sugar, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
