Why it works: Cinnamon and lemon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,950 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prunes
- Form the main filling, providing bulk, moisture and a rich, sweet fruit flavour.
- Eggs
- Egg whites beaten into meringue create a light foam that sets into the topping.
- Sugar
- Sweetens the filling and helps stabilise the beaten egg white meringue.
- Lemon juice
- Adds acidity that brightens the sweet prune filling.
- Pie crust
- Holds the filling in shape and gives the pie its base structure.
- Cinnamon
- Adds warm aroma that complements the cooked prunes.
The step that matters
Spread the meringue over the hot filling. Meringue spread so it touches the crust all round helps it seal and hold its shape. Egg white foam can shrink or weep if it is under-whipped or badly set, so beat it until stiff and bake it until lightly golden.
Swap the lemon
How well each one fits the dish's main ingredients (cinnamon, sugar, egg):
- Vanillafits better
- Raisinfits better
- Figfits about as well
- Lemonthe original
Fit is the average pairing score against cinnamon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
