Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 400°F (200°C).
In a bowl, mix the sugar, eggs, lemon extract, and sifted flour with baking powder.
Shape and bake
Take a tablespoonful of the mixture and drop it onto buttered paper or pans, moving your spoon along as you drop them to form shapes about three inches long and one inch wide.
Bake until golden, then sandwich two together with jelly in between.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Builds the structure that holds the batter's shape while it bakes.
- Eggs
- Add structure and moisture, helping the batter rise and set.
- Sugar
- Adds sweetness and helps the crust brown as it bakes.
- Baking powder
- Releases gas during baking, lifting the batter so it rises and becomes light.
- Lemon extract
- Adds a bright citrus aroma to the finished cookies.
The step that matters
Spacing and sizing the drops. The batter spreads as it bakes, so drops that are too large or placed too close together can merge and bake unevenly.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, flour, egg):

- Figfits about as well
Fit is the average pairing score against sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
