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 ↓
Soup Sticks with Baking Powder
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 400°F (200°C).
Rub the butter into the flour.
Mix in the baking powder and sugar.
Add enough milk to form a dough slightly firmer than tea biscuit dough.
Shape and bake
Let the dough rest for a moment.
Form the dough into strips.
Brush the strips with milk before baking.
Bake until crisp.

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
- All-purpose flour
- Forms the main structure that holds the strips together as they bake.
- Baking powder
- Releases gas in the oven, helping the sticks rise and become light.
- Butter
- Adds fat that rubs into the flour, tenderizing the texture and adding richness.
- Sugar
- Adds mild sweetness and helps the surface brown during baking.
- Milk
- Hydrates the flour to form the dough and helps the surface brown when brushed on.
The step that matters
Adding the milk. Flour absorbs liquid gradually, so too little milk leaves the dough crumbly and too much makes it sticky and dense. Aiming for a dough slightly firmer than tea biscuit dough gives strips that hold their shape and bake up crisp.
