Oven, in the book's wordsA steady oven

Ingredients

Directions

The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Sift flour and salt together.

  2. Pour in warm water and dissolved yeast; let rise for 4-5 hours.

  3. Add beaten eggs, sugar, and butter; mix well.

Shape and bake

  1. Shape into small rolls and place closely together in a pan.

  2. Cover with a cloth and let stand until light.

  3. Bake in a steady oven at 350°F (175°C).

  4. Before removing from the oven, wash the tops with beaten egg mixed with a little sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Provides the structure that holds the dough together and sets during baking.
Yeast
Produces gas that makes the dough rise and become light.
Eggs
Add structure and richness, helping the crumb set and the dough bind.
Butter
Adds fat that tenderizes the crumb and contributes flavor.
Sugar
Adds sweetness and helps the tops brown in the oven.

The step that matters

Let the dough rise until light. Yeast needs time and warmth to produce enough gas to lighten the dough. Under-proofed dough bakes dense, while over-proofed dough can collapse and lose its structure.
