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 ↓
Taffy Rolls
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 the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix flour and baking powder.
Add butter and enough milk or water to form a dough.
Roll the dough to ½ inch thick.
Fill and bake
Spread 1 cup of butter and 1 cup of creamed sugar over the dough.
Roll the dough sheet tightly and cut into ½ inch thick slices.
Place the slices on a baking sheet and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough once mixed with liquid.
- Baking powder
- Releases gas in the dough, helping the rolls rise and turn light.
- Butter
- Adds fat for tenderness and richness, and melts into the layers while baking.
- Creamed sugar
- Sweetens the filling and helps the surface brown in the oven.
The step that matters
Rolling and slicing the dough sheet. Rolling the dough tightly keeps the butter and sugar layers distinct inside each slice. A loose roll or uneven thickness lets the filling leak out and bake unevenly.
