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

What each ingredient does

Egg
Yolk thickens the vegetable mixture as it cooks, and the beaten egg on top helps it brown.
Bread crumbs
Form a crisp, golden topping on the surface when fried or baked.
Potatoes
Starch helps the cooked vegetable mixture thicken and hold together on the toast.

The step that matters

Cooking the vegetable mixture over low heat. Low heat lets the egg yolk thicken gently without scrambling. High heat can curdle the yolk and dry out the vegetables, leaving a grainy, uneven spread.

Swap the peas
