Why it works: Flour and sugar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓
Pineapple Pie
Ingredients
Directions
Make the filling
In a bowl, mix together the flour and sugar until well combined.
Add the grated pineapple pulp and juice, then stir and cook over medium heat until the mixture boils and thickens.
Remove from heat and stir in the beaten egg.
If using canned pineapple, add sugar gradually until the desired sweetness is reached.
Assemble and bake
Pour the filling between two pie crusts and bake.

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
- Flour
- Thickens the filling as it cooks, giving it body.
- Sugar
- Adds sweetness and balances the tartness of the pineapple.
- Grated pineapple pulp and juice
- Provides the main fruit flavor and liquid for the filling.
- Egg
- Adds richness and helps set the filling once it is stirred in.
The step that matters
Stirring in the beaten egg off the heat. Egg proteins set when hot and can curdle or scramble if added to a boiling mixture. Removing the pan from heat first lets the egg thicken the filling gently and evenly.
Swap the pineapple
How well each one fits the dish's main ingredients (flour, sugar, egg):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Pineapplethe original
Fit is the average pairing score against flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
