“Most of our customers are buying the large-size models that sell for $650,” Alexander said. “Sales of the egg as well as our Holland grills have been strong ever since Memorial Day. We’ve seen a few more customers coming in this week to purchase grills. It’s primarily customers who have one Big Green Egg and want to buy another one so they can cook two different types of meat at once or take one camping.”

Company information says the Big Green Egg is fueled by hardwood charcoal, which burns hotter than briquettes. Just about anything can be done with this odd-looking grill, including slow-cooking a beef brisket for 18 hours; searing rib-eye steaks over hot flames to juicy perfection; or blazing the Egg up to 750 degrees to bake thin-crust pizza in a couple of minutes.

Devotees of the grill, which has developed a sort of cult following, refer to themselves as Eggers or Eggheads. They share cooking tips in online chat rooms and even gather for an annual EggFest in Waldorf, Md.
