I broiled some beef koftes last week because I don't currently have a grill. They were on a rack set in a half sheet pan lined with foil. 3/4 of the way through cooking, the drippings started to smoke, setting off all the smoke alarms. I thought I read in a magazine that I could put something on the baking sheet to absorb the drippings so they wouldn't smoke. Salt, or baking soda maybe? I can't remember and I can't find the magazine either. Opening all the doors and windows isn't the most practical solution at my house, the cats always try to escape/shred my window screens.
