Preparing seafood

Buy live prawns and clams from your fishmonger. If you are sold them in a plastic bag, put a hole in it to ensure an oxygen supply. Keep them as cool as possible on your journey home. As soon as you get home throw them into a large bowl or bucket of water with some salt added and a teaspoon or so of flour.
When you need to prepare them, you don't need to do much to clams other than rinse them and throw out any that aren't closed. Give them a good shake. If any of them remain open when you give them a hard rap with your knuckles, throw them away. Use a sharp knife to scrape off any barnacles from the mussels. The mussels have a furry bit that sticks out from the inner curve of the shell. It's called a beard. Use your knife to pull this away.
