Most frozen prawns have been pre-cooked in salted water before freezing. The prawns were cooked from frozen. This results in the prawns shrinking and giving off too much water during cooking. If using pre-cooked frozen prawns always defrost thoroughly overnight in a fridge and drain well. Add the prawns for at most a minute towards the end of the cooking so that they are merely being reheated.
Rice noodles tend to stick together when stir-frying .
Soak the noodles in boiling water for no more than 5 minutes. Rinse and drain thoroughly, until dry. Add the oil and stir-fry the meat and vegetables before adding the noodles. When you add the noodles stir in a little extra oil to prevent sticking. Stir-fry quickly to heat through and serve immediately.
