Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Lemon Snaps
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix sugar, butter, and baking soda together for 5 minutes.
Rub in the eggs well.
Add flour, cream of tartar, and lemon extract, and mix thoroughly.
Place the mixture on a table.
Shape and bake
Break off a portion and roll it into a log about 1 inch in diameter.
Break off small pieces the size of a walnut.
Place them on a greased pan about 3 inches apart.
Flatten each piece to the size of a silver dollar with your palm.
Bake in a moderate oven (350°F) for 8 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the dough and helps the snaps brown and crisp as they bake.
- Butter
- Adds fat for richness and tenderness, and helps the dough hold together.
- Eggs
- Bind the dough and add moisture and structure.
- Flour
- Provides the structure that holds the snaps together as they bake.
- Baking soda
- Reacts with the dough to help it spread and rise slightly while baking.
- Cream of tartar
- Adds acidity that stabilizes the dough and supports the leavening.
The step that matters
Flatten each piece to the size of a silver dollar. Flattening sets how far the dough spreads in the oven. Pieces left too thick stay puffy and dense, while pieces pressed too thin can burn before they are cooked through.
