If you're looking for even heat distribution across your grill, a diffuser is a great tool to use. By evenly distributing the heat, it helps prevent hot spots and ensures that your food cooks evenly. Additionally, it can help keep the temperature of your grill more consistent, which is ideal if you're cooking over long periods of time.
When using a diffuser, it's important to keep an eye on the temperature of your grill and adjust as needed. This will help ensure that your food doesn't get overcooked or burnt. If you're new to using a diffuser, it's always best to start with lower temperatures and work your way up until you find the sweet spot for your particular grill.
