Make skewers easy to turn and prevent slipping of ingredients on skewers by putting two skewers through a little bit apart.
Blanch peppers, onions, celery, potatoes and any other vegetables that normally require longer cooking time than the other skewered ingredients so that all will be equally done when served.
Preheat a gas grill and be sure that racks and grills are well oiled to prevent sticking.
Keep tips of skewers sharp for easy spearing. Use finely pointed ones - bamboo are best - for such foods as water chestnuts, mushrooms, bay scallops and cauliflower, which tend to split if speared with blunt skewers.
Choose skewer ingredients for color and texture.
If using a baste with sugar, wait until foods are nearly done. Once cooked skewers can be "sauced" and then wrapped tightly in foil. Sugar bastes or Sauces can burn easily.
If using bamboo skewers, soak them in water for an hour before use so that they will not burn as easily.
