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

What each ingredient does

Kidney beans
Provide the bulk and protein-rich body of the filling.
Sweet potatoes
Add starch and natural sweetness that soften into the filling as it simmers.
Sweetcorn
Pureed into a thick base that forms the topping.
Egg
Binds the cooled sweetcorn topping so it sets when baked.
Cornmeal
Thickens the pureed sweetcorn so it holds together as a topping.
Dark chocolate
Adds depth and bitterness that rounds out the spiced filling.

The step that matters

Let the sweetcorn mix cool before adding the egg. Beating raw egg into a hot mixture can scramble it, so the topping may not set smoothly and evenly during baking.
