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 ↓

Loaf Cake

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 your oven to 350°F (175°C).

Make the batter

In a large bowl, cream together the butter and sugar until light and fluffy.
Beat in the eggs one at a time, mixing well after each addition.
Gradually add the flour, mixing until just combined.
Stir in the milk, sweet emptyings, cinnamon, and rose water.

Bake

Pour the batter into a greased loaf pan.
Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

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 once its proteins set during baking.
Butter: Adds richness and tenderness, and helps trap air when creamed with sugar.
Eggs: Bind the batter and add structure and moisture as they set.
Sugar: Sweetens the cake and helps create a light texture when creamed with butter.
Milk: Adds moisture and loosens the batter to a pourable consistency.
