Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Raisin Pie
Ingredients
Directions
Prepare the raisins
Seed the large, soft raisins and soak them in 1 cup of cold water for 2 hours.
Make the filling
Beat the egg until light, then mix in the sugar, lemon juice, and grated lemon rind.
Add the flour and mix well.
Stir in the soaked raisins and the water they were soaked in, and cook until the mixture thickens.
Bake and serve
Pour the filling into a pie crust and cover with a second crust.
Bake until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Beaten egg helps bind the filling and set it as it cooks.
- Flour
- Thickens the filling as it cooks, giving it a spoonable body.
- Sugar
- Sweetens the filling and balances the tart lemon.
- Raisins
- Provide chewy texture and concentrated sweetness throughout the filling.
- Lemon
- Adds acidity and bright aroma that cut through the sweetness.
The step that matters
Cooking the filling until it thickens. Flour and egg must be heated enough to swell and set. If the filling is undercooked it stays runny and can soften the bottom crust once baked.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, flour, raisin):
- Vanillafits better
- Figfits better
- Lemonthe original
- Datesfits about as well
Fit is the average pairing score against sugar, egg, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
