Don't use a strip-type thermometer, which you hold on your baby's forehead, to check your baby's temperature. Strip thermometers only show the temperature of your baby's skin, not her body. It's also best not to use an old-fashioned, mercury-in-glass thermometer.
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).
Drain and set aside until shrimp is done marinating. Wrap bacon around shrimp and skewer or secure with toothpick. Grill or broil until shrimp is done and bacon is crisp. This takes around 10 to 15 on both my grill and broiler, but you will need to judge this for yourself. Be careful to not overcook if using pre-cooked shrimp.
