Broiling pork on bamboo stick

I always wanted to find out how to cook pork so that it's crispy outside and tender within. After consulting a few people's methods, I decided to try out the following:

Recipe: Broiled pork on bamboo stick

Ingredients:
- 2 palm-sized pork sirloin steak, cut into 2" thick strips
Marinate:
- 1 teaspoon (tp) salt
- 1/2 tp white sugar
- 3 cloves garlic, finely chopped
- 1/4 tp five-spice powder (五香粉)
- 1 TB cooking wine
- 1 TB light soy sauce
- 1 TB dark soy sauce
- 2 tp sesame oil
BBQ sauce:
- 1 tp light soy sauce
- 1 tp dark soy sauce
- 2 TB honey
- 1 TB oil

Procedure:
1. Mix all ingredients of marinate. Rub onto all surfaces of pork and give it a little massage. Let sit in fridge overnight. Before cooking rinse off all seasoning.
2. Mix BBQ sauce ingredients to form a smooth thick paste. Rub generously and thoroughly on each strip of pork. Push a bamboo stick longitudinally through each strip of pork. Then use one stick to pierce perpendicularly through the center of all strips to form a bamboo rack. Place rack on a deep baking pan so that pork does not touch the pan. Broil at 425F on top rack for 5 minutes. Apply BBQ sauce again. Flip the bamboo rack to broil the bottom side for 5 minutes.
