Why it works: Red currant and lemon work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 309 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Whortleberry Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare and bake
Wash and pick over the whortleberries.
Place the berries in a pie dish, an inch thick, on the bottom crust.
Cover the berries thickly with sugar.
Add the upper crust and bake at 400°F (200°C) for 30 minutes.
Finish and serve
Mix in a few red currants (optional).
Sprinkle lemon juice among the berries (optional).
Sift powdered sugar over the pie before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whortleberries
- Provide the main filling, with their fruit flavour and juice.
- Sugar
- Sweetens the berries and draws out their juice as the pie bakes.
- Pastry
- Forms the upper and lower crust that hold the juicy filling.
The step that matters
Cover the berries thickly with sugar. Sugar sweetens the fruit and draws out its juice. Enough sugar keeps the filling sweet and balances the tartness of the berries.
Swap the red currant
The recipe marks red currant as optional. How well each one fits the dish's main ingredients (sugar, lemon):
- Orangefits better
- Limefits better
- Vanillafits better
- Red currantthe original
Fit is the average pairing score against sugar, lemon. 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.
