If you’re cooking kebabs or yakitori, be sure to soak the wooden skewers for at least 30 minutes before to prevent them from catching on fire.
This is false. Per the Spruce Eats:
Most recipes for kebabs and skewered food say to soak bamboo skewers in cold water for 30 minutes to prevent them from catching fire on the grill. But the reality is that the amount of water that a bamboo skewer can hold after soaking probably won’t fill a thimble. This is hardly enough water to keep the skewers from catching fire and any water they do hold will evaporate in a matter of seconds. To prevent bamboo skewers from burning, try placing a piece of aluminum foil under the exposed ends to protect them.
