Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Rusks, or Tops and Bottoms

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 dough

  1. Beat the eggs and add them to the yeast and a little milk.

  2. Sift the flour and mix it with the egg mixture to create a sponge.

  3. Melt the butter and add enough milk to achieve a dough-like consistency.

  4. Let the dough rise in a kneading trough until well risen.

Shape and bake

  1. Shape the dough into small loaves the size of teacups.

  2. Flatten the loaves.

  3. Bake the loaves in a 350°F (175°C) oven.

  4. Remove the loaves from the oven.

  5. Cut the tops from the bottoms of the loaves.

  6. Dry the loaves on tin plates in the oven until nicely colored.

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

Eggs
Bind the mixture and add richness and structure to the dough.
Yeast
Leavens the dough so it rises and becomes light before baking.
White flour
Forms the gluten network that gives the dough its structure.
Butter
Adds fat, which softens the crumb and gives a richer texture.

The step that matters

Let the dough rise in a kneading trough until well risen. Yeast needs time to produce gas and expand the gluten network. If the dough is underproofed, the rusks will be dense; if it is left too long, the structure can weaken and collapse.
