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

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

  2. In a bowl, combine the baking soda with the vinegar and stir well.

  3. Add the flour and mix until combined.

  4. Beat the eggs until light and fluffy, then add to the mixture.

  5. Gradually add warm water to form a stiff dough that can be rolled out.

Shape and bake

  1. Roll out the dough to 1 inch thick and cut with a biscuit cutter.

  2. Place the biscuits on a baking sheet and bake in the preheated oven.

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 dough once moistened and worked.
Baking soda
Reacts with the vinegar to produce carbon dioxide gas, which lifts the biscuits.
Vinegar
Acidifies the dough so it reacts with the baking soda to create rise.
Eggs
Add moisture and richness and help bind the dough.
Lard or butter
Adds fat that tenderizes the crumb and contributes flavor.

The step that matters

Combining the baking soda with the vinegar. The acid and base react quickly to release gas, so the dough should be shaped and baked soon after mixing to keep that lift from fading.
