Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lima beans
- Cooked and sieved, they form the thick body of the custard.
- Eggs
- Coagulate on heating, setting the custard into a soft, sliceable texture.
- Milk
- Adds liquid and richness, keeping the custard smooth and tender.
- Sugar
- Sweetens the custard and contributes to its browning at the surface.
- Butter
- Adds fat, giving the custard a richer mouthfeel and softer texture.
The step that matters
Baking in a water bath. Egg proteins set gently when surrounded by hot water. Direct oven heat can overcook the edges and make the custard grainy or watery, so the pan of hot water should be kept in place during baking.
Swap the lima beans
How well each one fits the dish's main ingredients (egg, milk, sugar, vanilla, butter):
- Almondfits better
- Pecansfits better
- Cocoafits better
- Lima beansthe original
Fit is the average pairing score against egg, milk, sugar, vanilla, butter. Candidates are from the same food group and used in at least 100 recipes.
