Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Provides a crisp, golden base that holds the toppings.
- Butter
- Frying the bread adds browning and a rich, savoury flavour.
- Prawn meat
- Forms the main savoury filling, giving the canapés their substance and flavour.
- Mayonnaise sauce
- Adds fat and creaminess, moistening the topping and softening its flavours.
The step that matters
Frying the bread until pale golden. Frying gives the bread a crisp, sturdy surface so it does not go soft under the wet topping. Cooling it fully before spreading also keeps the butter and filling from melting and sliding off.
