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 ↓

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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix molasses, butter, sour milk, and brown sugar until well combined.
Add baking soda and eggs, mixing thoroughly.
Gradually add flour, saving some for dusting the dates.
Fold in the chopped dates and mixed spices.
Bake
Pour the batter into a greased baking pan and bake for about 45-60 minutes, or until a toothpick comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the cake.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Molasses
- Adds moisture, dark colour and deep sweetness, and its acidity activates the baking soda.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Dates
- Add pockets of moisture and natural sweetness throughout the cake.
The step that matters
Adding the baking soda with the wet ingredients. Baking soda needs an acid, here the sour milk and molasses, to release carbon dioxide. Mixing it in promptly and then baking before the bubbles escape keeps the cake light instead of dense.
Swap the dates

Fit is the average pairing score against molasses, butter, milk, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
