I finally broke down and bought Patrick a new grill. The old one we had was (I think) a Walmart special that resembles more of a large metal cube than a grill. Turns out doing dinner parties for more than 4 people was a bit of a resource constrained affair.
For the benefit of those who do not know us, this is NOT a gas grill - gas bad. It's a nice little charcoal number with a crank that moves the bed of coals up or down. Lovely little thing - will try making pizzas on it tonight.
