Why it works: Sugar and flour 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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the filling
Preheat the oven to 350°F (175°C).
Beat the yolks of 4 eggs with ½ cup sugar and 2 tablespoons flour.
Mix in 1 pint of finely chopped pineapple thoroughly.
Add 2 cups of cold water and cook until thick.
Bake and top
Pour the mixture into a pie crust and bake until set.
Make a meringue by beating the 4 egg whites until stiff and spread over the pie.
Brown the meringue in the oven.

Egg and flour 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
- Egg yolks
- Thicken the filling and add richness as they set with heat.
- Flour
- Thickens the filling as it cooks, giving it body.
- Sugar
- Sweetens the filling and balances the tart pineapple.
- Pineapple
- Provides the main flavor and moisture of the filling.
- Egg whites
- Whipped into a meringue that gives a light, airy topping that browns.
The step that matters
Cook the filling until thick. The filling thickens as starch gelatinizes and egg yolks set with heat. Stopping too early leaves it runny, while overcooking can cause the yolks to curdle or scramble.
Swap the pineapple
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Pineapplethe original
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
