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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, mix the flour, sugar, and baking powder.
In another bowl, whisk together the milk, melted butter, and eggs.
Mix and bake
Combine the wet ingredients with the dry ingredients and mix until just combined.
Pour the batter into a greased baking dish.
Bake for 25-30 minutes or until golden brown.

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
- Flour
- Provides the starch and structure that hold the rusk together.
- Eggs
- Add structure and richness, helping the crumb set as it bakes.
- Baking powder
- Releases gas in the batter so the rusk rises and becomes light.
- Butter
- Adds fat for tenderness and flavour in the finished crumb.
- Milk
- Hydrates the flour and helps form the batter's texture.
- Sugar
- Adds sweetness and helps the top brown during baking.
The step that matters
Mix until just combined. Overmixing the batter after combining wet and dry ingredients develops gluten, which makes the rusk tough and dense rather than tender.
