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

What each ingredient does

Tomatoes
Hold the filling and soften into a juicy centre while the coating crisps.
Raw egg
Binds the herb and ham filling so it holds together in the tomato.
Light batter
Forms a golden coating that crisps in the hot oil.
Butter
Adds richness and browning to the filling and the toast.
Grated ham
Adds savoury flavour to the filling.

The step that matters

Fry the tomatoes quickly until golden. Frying briefly in hot oil sets and browns the batter before the tomato turns soft and collapses. Lingering too long lets the juices leak out and the coating turn greasy.

Swap the tomato

How well each one fits the dish's main ingredients (bread, butter, parsley, ham, egg, pepper):

  1. Shallotfits better
  2. Capsicumfits better
