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 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 300°F (150°C).
In a bowl, mix flour, baking powder, salt, and butter.
Add enough water to form a stiff dough.
Divide the dough into two pieces.
Roll each piece to a thickness of heavy pie crust.
Shape and bake
Place on white paper and cut into strips ¼ inch wide.
Bake between papers in the preheated oven.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: isobutyraldehyde (malty, green).
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
- Forms the main structure of the dough once mixed with water.
- Baking powder
- Releases gas to lighten the dough slightly as it bakes.
- Butter
- Adds fat that tenderizes the dough and contributes to its texture.
The step that matters
Rolling to an even thickness. Dough rolled to uneven thickness bakes unevenly, so thin spots can scorch while thick spots stay doughy. Keeping each piece an even heavy pie-crust thickness helps the strips bake through uniformly.
