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):

  1. Almondfits better
  2. Pecansfits better
  3. Cocoafits better
  4. 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.
