Prawns are shellfish. The name is used to describe small lobster-like shellfish, freshwater shrimp-like shellfish and very large shrimp. Use very large shrimp fir this recipe. Prawns are ideal for grilling because they are large enough to skewer easily, yet they cook very quickly.
If rosemary sprigs are not stiff, insert a wooden skewer along with the sprig when threading the prawns.
Prawns may be threaded on wooden skewers instead of rosemary sprigs. When using wooden skewers, add 1 teaspoon of chopped fresh rosemary leaves to the marmalade mixture. Add, soak the wooden skewers in water at least 15 minutes before threading the prawns.
