We detect a bit of voyeuristic interest among our readers on the topic of professional ranges. And we're looking for a new one, so let's start talking. We have cooked on a number of different rigs, and can say that our favorite is the commercial stoves we've used here and there - the stuff you can't buy retail. French Culinary Institute has Jade Ranges that almost make any cook feel like Mario Batali. And an old restaurant 6-burner DCS that I have the pleasure of cooking on in the summer has incredible power. From home in NYC, we're still battling it out with a 20" mystery-brand (Tappan? Kenmore? Who knows, the label wore off before I moved in), and in a few months, it will be history. As we scout about for its replacement, our chops have started watering considerably. We're going to take a look variety of what Consumer Reports calls Premium Ranges ($1,500 and up)l, starting with the Thermador 30" Pro Harmony All-Gas Range (P304CS). Those of you who own a heavy-duty range, don't hesitate to chime in. Those who dream of owning one, you're invited too.
