To Make Light Biscuit

Ingredients

• 1 teaspoon cream of tartar
• sour cream or milk
• baking soda

Directions

The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.

1. Use the usual amount of baking soda in the sour cream or milk.

2. Stir in 1 teaspoon of cream of tartar with the flour.

3. Bake in a hot oven (400°F / 200°C) until light and fluffy.
