This celebrated Broadway actor–-The Secret Garden, The Music Man, Mary Poppins–-much admired for her glorious voice, sees parallels between cooking and theater. Both are ephemeral.

None of this contradicts audience etiquette: no eating during the performance, and no cooking at your seat. Produced with Broadway on Demand, the video version can be seen–-seen!–-on their site
