Oven, in the book's wordsA brisk oven

Ingredients

Directions

The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

  2. In a bowl, mix the flour, baking soda, salt, and cream of tartar.

Make the dough

  1. Rub in the butter until the mixture resembles coarse crumbs.

  2. Gradually add the milk to form a stiff dough.

  3. Roll out the dough to ½ inch thick and cut into rounds.

Bake

  1. Bake in the preheated oven until golden brown.

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 of the biscuits as gluten develops with liquid and handling.
Butter
Rubbed into the flour to create tender layers and a crumbly texture.
Baking soda
Reacts with the acid in cream of tartar to release gas, helping the biscuits rise.
Cream of tartar
Provides acidity that reacts with baking soda to produce lift and a light crumb.
Fresh milk
Hydrates the flour to form the dough and adds moisture and browning from milk sugars.

The step that matters

Rub in the butter until coarse crumbs form. If the butter becomes fully incorporated or melted, the flour coats less and the biscuits turn tough or flat. Small cold butter pieces create steam and separate layers as they bake, giving a tender, flaky rise.
