Why it works: Lemon and cinnamon 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 ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Rub the butter and flour together in a bowl.
Add the sugar and beaten eggs.
Mix in the baking soda, lemon juice, cinnamon, and enough milk to form a dough.
Shape and bake
Roll out the dough into sheets.
Cut the cakes into diamond shapes.
Bake in the preheated oven until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Flour
- Forms the structure of the dough once combined with liquid and fat.
- Butter
- Adds fat that tenderises the dough and helps it brown.
- Eggs
- Bind the dough and add richness and structure.
- Baking soda
- Reacts with the acidic lemon juice to release gas, helping the cakes rise.
- Sugar
- Adds sweetness and contributes to browning in the oven.
The step that matters
Mix in the baking soda with the lemon juice. Baking soda needs an acid, such as lemon juice, to react and release gas. Dissolving it and mixing it in evenly helps the cakes rise uniformly rather than in patches.
Swap the lemon
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, cinnamon, milk):

Fit is the average pairing score against flour, sugar, butter, egg, cinnamon, milk. Candidates are from the same food group and used in at least 100 recipes.
