Why it works: Lemon and walnut match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,149 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
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.
Prepare the filling
Boil the raisins until soft.
Remove the pits from the raisins.
Chop the raisins and mix them with lemon juice, sugar, and butter.
Assemble and bake
Place the mixture between two pie crusts.
Bake at 350°F (175°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raisins
- Provide the main filling, with concentrated sweetness and a chewy body once softened.
- Sugar
- Adds sweetness and helps the raisin mixture become a moist, spoonable filling.
- Lemon juice
- Adds acidity that brightens the sweet raisin filling and balances its sweetness.
- Butter
- Adds fat for richness and a softer, more tender mouthfeel in the filling.
The step that matters
Boil the raisins until soft. Dried raisins are tough and need to rehydrate fully before baking. If they stay firm, the baked filling will be chewy and hard to cut rather than soft and spreadable.
Swap the walnut
How well each one fits the dish's main ingredients (raisin, lemon, sugar, butter):
- Almondfits better
- Pistachiofits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against raisin, lemon, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
