"What do those things do?", our dishwasher asks at the end of the night.
"Oh, they keep the water temperature constant so we can cook things for a really long time", tired after a long shift, and more tired of having to answer the same question a thousand times from everyone who comes in to the restaurant.
"Cool, so do you just vacuum seal the bags?"
"Uh, well yea, we do", somewhat caught off guard by his self-fulfilling question.
For some reason, sous-vide cooking, the lovable offspring of classical French cooking and modern technique, makes sense to everyone at first sight. Why? It doesn't seem intuitive, and even after being around it for close to a year now, I still sometimes feel it is somewhat cold and scientific. It's very strange not being able to pull the food out to taste it or smell it. The results are amazing, however, and for many foods, it enhances them so much that I wouldn't choose any other way.
On the other hand, you have the occasional person saying, "so I hear you cook everything in a bag for a long time. I hear that's the fancy French way of doing things".
How does this happen in a small town? I can only assume that the technique is becoming more commonplace in the American lexicon, and that it is less esoteric than all of us in the kitchen might think it to be. For so long, it seemed it was a little secret among chefs that were "in the know". Not so much, any more. And that's a good thing, in my humble opinion.
