Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the layers and give the pie its body and structure.
- Onions
- Add sweetness and savoury depth as they soften during baking.
- Bacon
- Adds fat and smoky, savoury flavour, and browns as it cooks.
- Eggs
- Set when heated, binding the milk into a firm, sliceable custard.
- Milk
- Adds moisture and creaminess, forming the custard with the eggs.
The step that matters
Bake until the top browns. The egg and milk custard only sets fully when heated through. Removing the pie too early leaves a runny centre that will not hold its shape when cut.
Swap the onion
How well each one fits the dish's main ingredients (potato, egg, pepper, milk):
