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 ↓

Directions
Prepare
Separate the eggs.
Butter your pan well.
Make the batter
Beat the yolks, sugar, and lemon juice and zest until thick and light.
Whisk the whites until dry. Add them with the flour, half of each at a time.

In a bowl, combine two cups molasses, sift two teaspoons soda and a dessert spoon ginger. Stir to a cream.
Add four well beaten eggs, one cup melted butter, one cup sour milk with one teaspoon soda dissolved. Mix all together.
Add flour to achieve the consistency of a pound cake.

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
- Eggs
- Whites trap air for lift, while yolks add richness and structure to the crumb.
- Flour
- Provides the structure that holds the sponge together as it sets in the oven.
- Molasses
- Adds moisture, dark colour and a deep sweetness to the cake.
- Butter
- Adds fat for tenderness and a rich, soft texture.
- Sour milk with soda
- Acid reacts with soda to produce gas that helps the cake rise.
- Sugar
- Sweetens the batter and helps the yolks whip to a thick, light texture.
The step that matters
Mix all together, but avoid beating.. Once flour is in, overbeating develops gluten and toughens the cake. Gentle folding keeps the air from the whites and the crumb tender.
