Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the mixture
Mix the flour and butter together.
Add the sugar and mix well.
Incorporate the treacle until combined.
Shape and bake
Drop teaspoonfuls of the mixture onto a buttered baking sheet.
Bake in a moderate oven at 350°F (175°C) until done.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Provides the structure that holds the mixture together as it bakes.
- Butter
- Adds fat that softens the batter and helps it spread thinly and crisp.
- Sugar
- Adds sweetness and helps the snaps brown and crisp as they bake.
- Treacle
- Adds sweetness, rich flavour, and colour, and makes the snaps chewier.
The step that matters
Bake in a moderate oven at 350°F (175°C) until done.. Sugar-rich mixtures brown quickly and can burn or turn bitter if baked too long. Removing them once golden and checking for doneness helps keep the snaps crisp rather than dark and brittle.
