Rusk or Sweet Bread

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the sponge

  1. In a large bowl, combine 4 cups of flour, 2 cups of sugar, 1 cup of melted lard, and 3 cups of water.

  2. Stir in 2 tablespoons of yeast to make a batter and let it rise overnight.

Make the dough

  1. In the morning, add 2 beaten eggs and 3 more cups of flour to the sponge and mix well.

  2. The dough should be soft; let it rise until light.

Shape and bake

  1. Form the dough into rolls and let them rise again until very light.

  2. Bake the rolls in a cool oven at 300°F (150°C) until golden.

  3. While warm, brush the rolls with egg white and sprinkle with ground cinnamon.

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 gluten network that gives the rolls their structure.
White sugar
Adds sweetness and feeds the yeast, and helps the crust brown.
Lard
Adds fat that tenderises the crumb and keeps the rolls soft.
Active dry yeast
Produces gas that makes the dough rise and become light.
Eggs
Add structure and richness to the dough.

The step that matters

Letting the dough rise until light. Yeast needs time and warmth to produce enough gas for a light texture; rolls shaped or baked before they are fully risen stay dense and heavy.

Swap the cinnamon

How well each one fits the dish's main ingredients (flour, sugar, egg):

  1. Jalapenofits about as well
  2. Cinnamonthe original
  3. Nutmegfits about as well
  4. Capersfits less well

Fit is the average pairing score against flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
