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 says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the beaten eggs and mix well.
Sift the cream of tartar with the flour twice.
Dissolve the baking soda in the milk and add to the mixture.
Fold in the chopped dates.
Bake
Pour the batter into a large cake tin.
Bake in a slow oven at 300°F (150°C) for about 1 hour and 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Provide structure and richness, setting the crumb as the cake bakes.
- Flour
- Forms the main structure of the cake once it is set by heat.
- Baking soda
- Reacts with the acidic cream of tartar and milk to lift the batter as it bakes.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to produce rising gas.
- Dates
- Add moisture and natural sweetness to the finished cake.
The step that matters
Dissolve the baking soda in the milk and add to the mixture.. Baking soda needs an acid to release gas efficiently. If it is not fully dissolved and evenly mixed, pockets of unreacted soda can cause bitter spots and uneven rising.
