Spring has sprung and the family cooking is shifting from "mom-in-the-kitchen" style to "dad-outdoors" mode. Since your barbecue grill has been sitting all winter, there are things you should do before firing it up. For gas grills, top off the LP tank and be sure burners are free of rust and debris. For charcoal barbecues, clean grill surfaces with a wire brush and add a light coat of cooking oil to prevent sticking. But if Old Man Winter and rust have teamed up, and your grill's a total bust, do what lots of other cooking dads will do in the next month or two. Hop in the car and head for the local hardware store. Buy a shiny new barbecue. Almost half of all grills sold annually are purchased in the months of May and June). If yours is beyond repair, don't despair. Join the crowd and get a new barbecue. And that's the On The House tip for today.
