Sweet Rusks

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Make the batter

  1. Cream butter and sugar together.

  2. Add the well-beaten yolks of the eggs, then the stiffly beaten egg whites.

  3. Sift in the flour and salt, then gradually add the milk.

Add yeast and rise

  1. Dissolve the yeast in warm water and add it to the mixture.

  2. Cover and let the dough rise until very light.

  3. Pour the dough into a buttered biscuit pan, filling it half full.

  4. Let it rise until the pan is quite full.

Bake and cut

  1. Bake in a moderate oven at 350°F (175°C) for thirty minutes.

  2. When done, cut into long narrow strips.

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

What each ingredient does

Butter
Creams with sugar to give the dough richness and a tender crumb.
Sugar
Sweetens the dough and helps it brown during baking.
Milk
Adds moisture that hydrates the flour into a soft dough.
Yeast
Produces gas that makes the dough rise and become light.
Flour
Provides the structure that holds the risen dough together.

The step that matters

Let it rise until the pan is quite full.. Yeast gas is what lightens the dough. Underproofed dough stays dense, while overproofed dough can collapse or turn coarse in the oven.
