how long to grill shrimp in the shell?
<answer> 3 to 5 minutes each side. <context> If your prawns are smaller, spread a piece of aluminum foil or banana leaf on the grill first, then place prawns on top. Or skewer the shrimp with satay sticks (if wood, soak in water first). Baste the prawns the first time you turn them with a little of the leftover sauce. Grill 3 to 5 minutes each side. Prawns are done when the flesh turns from translucent to pinkish-white (and the shells turn a very attractive bright pink).
