Onions cooked on wood coals and The Bunny Kitty. |
I am of the opinion that every restaurant kitchen could be made better by the inclusion of a wood burning something. Oven, grill, hearth. I say could be because there is ample evidence that bad cooking cannot be improved upon by live fire. Good cooking, however, can. I have gotten into more than one argument with an equipment engineer friend who extolls the virtues of gas and gas assist pizza ovens. He thinks that because the smoke only comes into play by perfuming the dining room that a serious cook, one who cares first and foremost about the results a given piece of equipment produces, would not choose a wood burning stone oven over gas. My opinion, is that he clearly has not spent enough time working with one.
I, however, have. First of all, I am not entirely convinced that gas fired stone ovens perform at the same level as solid fuel ovens. Gas ovens cannot be used efficiently for retained heat baking, which for me is one of the main reasons to own one. And regardless of what you're cooking, recovery time, convection, and chamber humidity are crucial to achieving excellent results. Smoke, as he points out, is only incidental. He is right about this, if you consider the aroma of wood smoke in a dining room as incidental (it is not). The smoke produced by a wood fired oven is icing, not cake. The foods cooked in a wood fired oven are not decidedly smoky, nor are they intended to be. It is continuous, uninterrupted intense heat that is responsible for the high quality of well made pizza crust, deeply caramelized meats, and candy sweet root vegetables. Can this heat be reproduced by a gas fired oven? Sometimes. Is it more than just incidental that the best you can hope for from a gas fired oven is that it might sometimes approximate the qualities of a wood oven? Absolutely.
Second, and more importantly, though my friend would probably be exasperated at this largely aesthetic supposition, wood changes something in the mind of a cook. Turning a burner on a gas range is done without thought. Building and tending a fire is always demanding of one's attention. A wood fire is wild and unpredictable. You cannot hope for behavioral consistency so you must always be vigilant. You must always, as Irma Baumbeck famously said, "stand facing the stove." A live fire forces the cook to engage, to identify, manage, and master idiosyncrasies with each fire, even hour to hour in the same fire. Instead of worrying only about what goes into the oven, you must tend to the oven itself. But great control and opportunity await the cook diligent enough to become skilled. This is admittedly a lot to heap on the shoulders of some nineteen year old who is only cooking because he can't settle on a major. For someone with blood of wood smoke and bones of fire brick, it is a constantly shapeshifting opportunity to shine.
Lemme s'plain: without a doubt the best thing I have ever smelled in my life was a failed loaf of bread.
I was obsessed with retained heat baking at Journeyman. When I learned what a real loaf of pumpernickel bread was about, I lost my mind. Today, pumpernickel is mostly a white flour "rye" bread made dark with the addition of dark beer or molasses or, in the worst loaves, some fake colorant. But traditionally, in the days when a German baker used a wood fired oven to bake bread, pumpernickel was loaded into an oven when it was not being refired to bake the following day. The slowly waning heat of the oven was the perfect environment to bake a dense, all rye loaf that could coast to doneness over twelve, maybe even sixteen hours of baking as the oven temperature slowly dropped. It got that dark, almost black color, by slowly baking at low temperatures, skirting the line between delicious and burned, not by the addition of other darkly colored things. This was the bread that the baker took home to his family. It was an intense sourdough that staled slowly, over the course of weeks, not days. It was nutrient dense, flavorful, and as luck would have it, a perfect mate to beer, sausage, and smoked fish.
I spent three weeks making a rye starter specifically for this bread. Four days fermenting the dough in precise stages. On a Sunday night after service, when we would be closed for the next two days and the oven would not be refired for next day's baking, I shaped ten or twelve loaves, loaded them into the softly radiating oven, and went home. When I came in the next morning, the aromas of that bread filled the entire restaurant. It was powerful, inescapable, but still warm and soft and elegant. I will never forget it. I won't try to describe it further. It is not possible. It can only be communicated through the nose. I thought I might cry for a moment. I was so sure I had tapped in to some deep culinary vein that had eagerly awaited a hero to unearth it.
But the bread wasn't good. The oven stayed too hot too long and the loaves were dried out and inedible. We had gone to great lengths when building the oven to insulate it so that it would retain heat for long bake days, and the modern materials we used to do so did their jobs well, too well for real pumpernickel. Something, I would venture to say, no one I know has actually tasted. And I knew it right away, the moment I lifted a loaf and felt its dry, steely, stubborn, unyielding texture in my fingers. I was the only one who would ever know the aroma of pumpernickel from the Journeyman oven, and even I would never know the taste. I didn't bother to try again. I knew our oven couldn't do it. For some reason, I just knew.
Natural gas does not yield such days.
In the fire pit behind me, there are onions roasting in dirty wood coals for the Harvest Dinner I am cooking a course for tomorrow. I don't remember how I came across it, but I find myself a little obsessed right now with escalivada, a Catalan dish of eggplant, onion, tomato, and bell peppers roasted in the coals of an open fire, usually served on bread with salt packed anchovy and olive oil. When I read about it I knew I had to find a home for it in my cooking. So the onions for my salad tomorrow got thrown skin on into the waning embers of a campfire. A fire I lit and enjoyed all by myself. An industrial carbon credit's worth of wood got burned to cook eight large red onions. It took the entire night from lighting, tending, burning wood down to coals, then finally cooking. I'm not sure they are done yet. But they smell good. Not as good as a loaf of failed pumpernickel, twelve hours into baking, but they are certainly making me hungry.
