When using wooden skewers for grilling, it's generally recommended to soak them in water before grilling. Soaking wooden skewers helps prevent them from burning or catching fire on the grill. The amount of time you should soak wooden skewers depends on their thickness, but a good rule of thumb is to soak them for at least 30 minutes.
By soaking the skewers, you add moisture to the wood, reducing the risk of flare-ups and charring. It's a simple step that can make a significant difference in the grilling process, especially when cooking with higher temperatures.
Remember to fully submerge the skewers in water while soaking, using a container or a ziplock bag. Once they have soaked for the recommended time, you can remove them from the water, drain off any excess, and thread your ingredients onto the skewers for grilling.
