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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, mix the milk and molasses together.
Melt the butter and add it to the mixture.
Gradually add the flour and baking soda, mixing until a dough forms.
Shape and bake
Roll out the dough on a well-floured surface to about ½ inch thick.
Cut into squares and place on a baking sheet.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the dough together and sets as it bakes.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Molasses
- Adds sweetness, dark colour and moisture, and contributes to the flavour.
- Milk
- Adds moisture to bind the dough and helps the surface brown.
- Baking soda
- Reacts with the acidic molasses to release gas, helping the dough rise.
The step that matters
Gradually add the flour and baking soda. Adding flour gradually lets it hydrate evenly and keeps the dough from becoming stiff or lumpy. Baking soda needs to be evenly distributed so it reacts with the acidic molasses throughout, giving an even rise and colour.
