Tips
Always buy fresh prawns for your cocktail. A good, fresh prawn will be shiny, unblemished, firm, and have a delicate and non-pungent aroma. If you are not sure of their freshness, use frozen ones. Another tip: before you eat your prawn cocktail let it rest for at least half an hour in the fridge, and if you don’t have time to make the cocktail sauce you can buy some ready-made at the supermarket. Finally, remember that the cocktail sauce must be creamy and thick, not runny.
Trivia
Prawns are low in fat and are suitable for diets if you remember not to complement them with overly rich dressings. Furthermore, they are rich in vitamin B and iodine, are easily digested and don’t contain gluten, so they are also suitable for those suffering from coeliac disease.
