Why it works: Raisin and flour 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 ↓
Lemon Raisin 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.
Make the filling
Combine the chopped raisins, lemon juice, lemon rind, cold water, flour, sugar, and butter in a bowl. Stir lightly until well mixed.
Cook the mixture in a double boiler until it thickens.
Assemble and bake
Pour the filling into a pie crust and cover with another crust.
Bake in a preheated oven at 350°F (175°C) until golden brown.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Add chewy texture and concentrated sweetness to the filling.
- Flour
- Thickens the filling as it cooks, giving it a set body.
- Sugar
- Sweetens the filling and balances the sharpness of the lemon.
- Lemon
- Adds acidity and bright aroma; the rind contributes fragrant oils.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the filling.
The step that matters
Cook the filling until it thickens. Flour thickens only when the mixture is heated enough for its starch to swell. If the filling is not cooked long enough, it stays runny and can soak the crust and make slicing difficult.
Swap the lemon

- Lemonthe original
Fit is the average pairing score against raisin, flour, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
