Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a quick 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).
Make the dough
In a large bowl, mix together the sugar, butter, sweet milk, lard, eggs, lemon oil, carbonate of ammonia, and salt until well combined.
Shape and bake
Roll the dough out thinly on a floured surface.
Use a fork to prick the rolled dough.
Cut into desired shapes and bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, and helps the crackers brown and taste rich.
- Lard
- Adds fat that keeps the crackers short and tender in texture.
- Eggs
- Bind the dough and add richness and structure.
- Granulated sugar
- Adds sweetness and helps the crackers brown as they bake.
- Carbonate of ammonia
- A leavening agent that helps the crackers rise and become crisp.
The step that matters
Rolling the dough thinly. Thin dough bakes through and crisps evenly. Thick dough stays soft in the middle and can brown unevenly before it dries out.
