Prawn Cocktail Sauce

My love affair with prawn cocktail sandwiches is bordering on an obsession. My Mom would often pack them with a little tin of Dr Pepper for school trip packed lunches. I think I've been conditioned to see them as special event food. Only now I'm having prawn cocktail sandwiches every other lunchtime.
Prawn cocktail and avocado sandwich

Ingredients (serves two)
50g prawns
2 tablespoons mayonnaise
1/4 teaspoon of tomato puree
A small pinch of cayenne pepper

Pat the prawns dry as any extra moisture dilutes the sauce and leads to a sloppy sandwich. This step is particularly important if you're using defrosted prawns.

Mix the mayonnaise and tomato puree together then sir in the cayenne pepper and prawns.

Serving suggestions - in sandwiches, over half an avocado or with shredded lettuce in a cocktail glass.
At Christmastime we add a splash of sherry to the sauce to make it a little more decadent
