Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sweet potatoes: Provide the main starchy body and moist, tender texture of the bread.
Banana: Adds moisture and natural sweetness, helping the bread stay soft.
Brown sugar: Adds sweetness and moisture, and helps the top brown during baking.
Evaporated milk: Adds liquid and milk solids that give a tender crumb and browning.
Coconut milk: Adds liquid, richness and fat, keeping the bake moist.
Butter: Adds fat for richness and a softer, more tender texture.

The step that matters

Bake until a toothpick comes out clean. The bake is wet and starchy, so it can look set on top while the center is still custardy. Testing the center with a toothpick confirms it is fully cooked before cooling.
