I don't spatchcock chicken normally. I believe the best method for roasting a quality bird is whole and trussed. I will rub an olive oil and herb, or clarified butter and rub paste under the breast skin prior to trussing. After trussing, a coating of rub on the skin. I truss so body cavities are closed up. Then, onto a rack or rotisserie if available. I like to roast at 400F, I tend to use lump for this and no smoke wood. At 400F, the wood just ignites anyways. Roast until done.
the meat thermometer was so far past the top reading, it read Taylor
"perhaps...but then again...maybe not..."
