What you can grill on a skewer
The ingredients you need for a skewer: barbecue sauce, pretzel powder, barbecue oil, five-spice powder, cumin powder, chili oil, sesame seeds and so on.
Grilled meat and fish are usually marinated for 1-2 hours in advance with soy sauce, salt, cooking wine, onion and ginger.
Different ingredients are best grilled in different ways, for example: meat is usually grilled directly over charcoal, and fish is usually simmered in a tinfoil box.
