We gave them 2 hours to get their grills going and finish their dishes before the guests arrived. I had done a test run on a grill in the parking lot days before to find out how long it would take to light the charcoal, get the grill hot and cause the charcoal to burn. I'm from upstate NY where barbecuing and summer are synonymous (though rare due to real estate). I jump at the chance to get on a grill here in the city whenever I can.
It was interesting that some of them had never gotten a grill going unless it was turning a knob on the gas grill in their respective kitchens. The challenge for most of the chefs was grasping cooking time on the grill and how their service was going to run once they began serving. This was also an opportunity for them to flex their salesman skills when dealing with the guests. In Brian's case: a used car salesman, and I say that in the most affectionate way.
