When you are buying fresh green prawns, look for a firm body and a pleasant 'sea' smell. Make sure you avoid any prawns which are turning black.
To store green prawns, place in an airtight container, covered with water. Keep in the refrigerator for a day or two. This will prevent oxidation.

A good steak is even beter with a little something. Try this creamy herb topping instead of fried mushrooms.
