Looking for some ideas for my dad. He has always been a cook and has had multiple “fancy” grills but now that he has retired my mom said they have no use for the oven and he’s grilling 100% of the meals nearly! He has a fancy smoker type grill. I know he has a griddle and has done pancakes on it and cookies and pizza as well as all the more obvious meats. Anyone got really unique ideas of grill related accessories or spices or anything for gifts?
