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 filling
Soak the raisins in 1 cup of cold water for 1 hour.
Beat the egg with the sugar until light.
Add the juice of the lemon and mix in the flour.

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
- Raisins
- Provide the main body of the filling, along with chewy texture and natural sweetness.
- Egg
- Helps bind and thicken the filling as it cooks, giving it a set structure.
- Sugar
- Sweetens the filling and adds body when beaten with the egg.
- Flour
- Thickens the filling, helping it hold its shape once cooked.
- Lemon
- Adds acidity that brightens the sweetness of the raisins and sugar.
The step that matters
Cook the mixture in a double boiler until it thickens. Gentle, indirect heat lets the egg and flour thicken the filling evenly. Overheating can curdle the egg or scorch the mixture, so it should be stirred and cooked only until it thickens.
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.
