This episode of Chef's Table may be the best if all the series. Some episodes in the 1st and 2nd seasons rival it, but this is at least tied for best. The Director, here, found the perfect blend of narrative attention on the Chef and the food. It's excellence is likely driven by the Chef, himself, in that he (Sean Brock) is so focused on the food and the basis of his purpose and cuisine, rather than being a celebrity or telling some other kind of story.
Far too many episodes in seasons 3-6 have drifted into melodrama narratives and pseudo-celebrity, and put the purported purpose of Chef's Table onto the back burner. Producers either list the vision or let Directors run away from it. It's also possible that too many Directors and Producers simply weren't interested in the original focus of the series, or weren't competent to build episodes appropriately.
Chef's Table is renewed for two more seasons. I hope they've learned from the wasted 'fluffy', foamy episodes - insubstantial and unsatisfying, despite having superficial beauty and a sense of elegance - and will FOCUS on producing consistently high-quality products for viewers to consume.
