I tried this at a friend's house and it was finger licking good! He was able to give me the ingredients, so here is my measurements that goes with the recipe:
3 Tbsp Honey
3 tsp Shoyu
drops of hot sauce (the rooster one is best but any viet ones are just fine)
drops of Worchestershire sauce
crushed Hawaiian Salt
3 cloves minced garlic
Put them all together in a ziploc bag and marinade in the fridge for about an hour before grilling. Peeled shrimp would be about 4-5 minutes on one side and then 3 minutes on the other side or until it turns pink, if you cook it too long it'll turn dry. If it's not peeled, it can be cooked alittle longer or until the shells are crunchy. Some likes to eat with shell on because of this. I like to lick/suck the shell first and then peel it and then eat the inside.
