Ingredients: 4 cups all-purpose flour; 2 tablespoons butter, chopped; cold water, as needed; 2 teaspoons cream of tartar; 1 teaspoon baking soda; ¼ teaspoon salt

Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Soda Biscuit Without Milk

Oven, in the book's wordsA quick oven

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 large bowl, mix the flour, cream of tartar, and salt.
Cut in the butter until well incorporated.
Dissolve the baking soda in cold water and quickly mix into the dough.
Handle the dough as little as possible; it should be stiff enough to roll out.

Shape and bake

Roll the dough to ½ inch thick and cut out biscuits.
Bake immediately in the preheated oven until golden.

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 structure of the biscuits as gluten develops with handling.
Butter: Cut into the flour to create tenderness and flaky layers as it melts in the oven.
Cream of tartar: Reacts with baking soda to produce carbon dioxide, helping the biscuits rise.
Baking soda: Provides the alkali that reacts with cream of tartar to leaven the dough and aid browning.

The step that matters

Handle the dough as little as possible. Once cold water and baking soda are mixed in, the acid-base reaction starts and gluten forms with handling. Overworking makes the biscuits tough, so mix quickly and bake right away.
