First day with the PB24 and I'm doing a spatchcock chicken as my inagural cooking adventure with the kamado. Halfway through and I'm wondering if all the smoke pouring out of the top vent is 'normal'? I'm stable at 375 and am cooking direct heat on top rack, no diffuser. My GF is giving me the evil eye because she thinks I'm smoking the house out every time I open the patio door to come in! I keep telling her I'm not smoking the chicken, I'm ROASTING it... but the smoke isn't helping my case. Help a newbie out?
