Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Provides the crisp, golden base that holds the toppings.
- Butter
- Frying fat that browns the bread and adds richness.
- Green butter
- Adds fat and flavour between the bread and the seafood topping.
- Prawn or lobster meat
- Main topping that supplies the seafood flavour and savoury body.
- Mayonnaise sauce
- Adds richness and moisture to the topping.
The step that matters
Fry bread in butter until pale golden. Frying gives the bread a firm, crisp surface that resists soaking up moisture from the topping. Browning too far turns it bitter, and undercooked bread stays soft and soggy.
