To Make Rusks

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.

Make the dough

  1. Combine the milk and butter in a saucepan.

  2. Heat gently until the butter is melted.

  3. Mix the flour and sugar together in a bowl.

  4. Beat the eggs and stir them with the yeast into the milk and butter mixture.

  5. Combine the liquid with the flour to form a smooth dough.

  6. Cover the bowl with a cloth.

  7. Let the dough rise near a warm place.

  8. Knead the dough.

Bake and dry

  1. Divide the dough into twelve pieces.

  2. Place the pieces in a preheated oven at 400°F (200°C) and bake for about 20 minutes.

  3. Remove the rusks.

  4. Break them in half.

  5. Return them to the oven to crisp the other side.

  6. Once cooled, store them in tin canisters to keep dry.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Flour
Forms the structure of the dough that holds the rusks together.
Eggs
Add richness and help bind the dough and give it a tender crumb.
Butter
Adds fat for a tender texture and rich flavour.
Yeast
Produces gas that makes the dough rise before baking.
Milk
Provides moisture that hydrates the flour and forms the dough.
Loaf sugar
Adds sweetness and helps feed the yeast while browning the crust.

The step that matters

Let the dough rise near a warm place. Yeast needs warmth to produce gas, and the dough must rise fully before baking so the rusks become light rather than dense. Covering the bowl keeps the surface from drying and forming a crust.
