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 ↓

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.

Prepare

  1. Heat the milk and melt the butter in it.

  2. Add the yeast to the milk and butter mixture.

Make the dough

  1. Work the flour into a smooth dough using the liquid.

  2. Cover the basin with a cloth and let the dough rise by the fire.

  3. Knead the dough and divide it into twelve pieces.

Bake and store

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

  2. Remove the rusks, break them in half, and return them to the oven to crisp the other side.

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

Butter and flour 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 as its proteins bond with the liquid.
Milk
Supplies the liquid that hydrates the flour and adds softness.
Butter
Adds fat that tenderises the crumb and carries flavour.
Yeast
Produces gas that makes the dough rise before baking.

The step that matters

Returning the broken rusks to the oven. Baking the cut faces again drives off remaining moisture, which is what gives rusks their dry, crisp texture. If they are left soft inside, they will go stale quickly in storage, so the second bake should be thorough.
