If anyone remembers from around fall last year, I did a stage at Moto in hopes of making it into Chef Cantu's kitchen. The job was offered, but my school schedule was unable to match his.
I met Ben Roche, the pastry chef in question here. If you do a youtube search for either Homaro Cantu or Ben Roche, you are going to come up with a few good videos demonstrating their use of liquid nitrogen or other interesting cooking methods. Talking about liquid nitro, I noticed aa dish named "snow", where specially prepared goat cheese is plunged into liquid nitrogen and served to the customer smoking. Hard to describe, but definitely something very pleasant.
A very good episode to watch is the episode of Iron Chef America where Homaro Cantu (Moto) takes on Iron Chef Morimoto in a Beet battle.
