I was given this tip, back in the mid 1980's when I used to visit a shop called Bruccianis, in good old Barrow-in-Furness, who made the best sandwiches in the world!

Prawns on their own are dry, don't taste of much, etc. Instead of wasting your money on 1000 island dressing and the like, try this:

Take 2 parts salad cream, mix it with 1 part tomato sauce (I use heinz out of a glass bottle as the "squeezy" bottle is normally alot thinner than the glass bottle stuff) mix well together, spread on one side of a muffin/teacake/bap, add prawns, add a lettuce leaf and maybe some cucumber, then scoff before someone else can eat it.
