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 ↓

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, with the custard, add structure and richness to the layers.
- Butter
- Adds fat for a tender crumb and rich flavor in the cake.
- Flour
- Forms the main structure of the cake batter as it sets in the oven.
- Corn starch
- Thickens the milk so the custard sets into a spreadable filling.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Hickory-nut meats
- Add crunch and a nutty flavor to the custard filling.
The step that matters
Adding the corn starch to the boiling milk. Corn starch must be dissolved in cold or cool milk first, then stirred into hot milk; added dry or lumpy it clumps and the custard turns grainy instead of smooth and thick.
