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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the sugar and butter together.
Beat in the eggs, then add the saleratus water and lemon juice.
Mix in the flour and cinnamon, adding enough milk to make a rather stiff dough.
Knead the dough until smooth.
Shape and bake
Roll it out to ½ inch thick and cut into diamond shapes.
Bake in a moderate oven at 350°F (175°C) 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
- Butter
- Creams with the sugar to add richness and a tender crumb.
- Eggs
- Bind the batter and add structure and richness to the cake.
- Saleratus
- Reacts with the acidic lemon juice to release gas, helping the cake rise.
- Flour
- Provides the main structure once mixed into the dough.
- Sugar
- Sweetens the cake and helps browning during baking.
The step that matters
Adding the saleratus water and lemon juice. Saleratus is a leavening agent that needs an acid to react and release carbon dioxide. Mixing it in with the lemon juice at the right point lets the gas form in the batter, so the cake rises evenly instead of staying dense.

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