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 ↓

Breakfast Rusk

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the batter

  1. Preheat the oven to 400°F (200°C).

  2. In a large bowl, mix the flour, sugar, cream of tartar, and baking soda.

  3. In another bowl, whisk together the milk, eggs, and melted butter.

  4. Combine the wet and dry ingredients until just mixed.

Bake and serve

  1. Pour the batter into a long pan and bake for about 25-30 minutes.

  2. Once baked, cut into pieces like sponge cake.

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

What each ingredient does

Flour
Provides the main structure that sets as the batter bakes.
Cream of tartar
Acidifies the batter so it reacts with baking soda to help it rise.
Baking soda
Reacts with the acid in the batter to produce gas that lightens the crumb.
Eggs
Add structure and moisture, helping bind the batter as it sets.
Milk
Adds moisture and helps hydrate the flour to form the batter.

The step that matters

Combine the wet and dry ingredients until just mixed. Overmixing develops gluten in the flour, which can make the rusk tough. Mixing only until combined keeps the texture tender while the leavening reacts.
