In the example in this question I mention getting the grill to 400 Fahrenheit. This example is not in a vacuum. I really do need to roast my brussels sprouts at 400 Fahrenheit and I won't necessarily have oven space as it is Thanksgiving. So my question has evolved. Most charcoal grill recipes I have read involve temperatures in the 200 to 300 Fahrenheit range. Can I get a charcoal grill (for this example consider a Weber kettle grill) to 400 Fahrenheit and keep it there consistently?
Also, if I add smoking wood, will that change a lot? I am glazing brussels sprout in black pepper, bacon, and maple syrup if it matters and I will smoke them with whatever is available at the house. The recipe I am using involves roasting them in a pan, so I would prefer to keep it that way (lest I have to clean the grill).
