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

What each ingredient does

Cold boiled potatoes
Form the main body of the dish and brown into a crisp crust on the outside.
Butter
Adds richness and helps the potatoes brown in the hot pan.
Flour
Browned in butter to thicken the gravy as it cooks with the water.
Onion
Flavours the gravy and lightly seasons the pan before the potatoes go in.
Tomato ketchup
Adds sweetness and acidity to the finished gravy.

The step that matters

Brown the potatoes in a very hot pan. The pan must be very hot before the potatoes go in, so the surface browns and crisps instead of steaming. Crowding or a cool pan leaves the potatoes soft and pale.

Swap the tomato

How well each one fits the dish's main ingredients (potato, onion, flour, butter, pepper, ketchup):
