Why it works: Butter and milk 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

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 dough

  1. Work the butter into crumbs with the flour until well combined.

  2. Mix in the beer, beaten eggs, and fresh milk to form a smooth paste.

  3. Let the dough rise until it has doubled in size.

  4. Knead the dough until smooth, then shape it into small loaves or thick cakes using a round cutter.

Bake and dry

  1. Place the shaped dough on a floured baking sheet and let it prove in a warm place for 10 to 20 minutes.

  2. Preheat the oven to 300°F (150°C).

  3. Bake the rusks for about 15 minutes until lightly golden.

  4. While still warm, divide the rusks and place them back in the oven to dry until crisp.

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

What each ingredient does

Flour
Forms the main structure of the dough as its proteins bind with liquid.
Butter
Adds fat that tenderises the crumb and carries flavour.
Eggs
Bind the dough and add richness and structure.
Milk
Adds moisture and helps form a smooth paste with the other liquids.
Beer
Adds moisture and a light fermented flavour to the dough.

The step that matters

Drying the rusks until crisp. Rusks are twice-baked to remove moisture so they keep their crispness. Leaving them too moist after the first bake, or drying them unevenly, leaves them soft and prone to spoiling.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
