I'm curious about marinating something under pressure versus in a vacuum. The Modernist Cuisine at Home describes a way of marinating inside of a whipping siphon by adding pressure to the marinade. On the other hand, I own a vacuum sealer that came with a specialized container with a hose in the top that attaches to the vacuum, used to marinate. From what I have read, the principle is that the vacuum helps "open the fibers and pours of the meat, allowing the marinade to penetrate more quickly".
Considering these approaches are exact opposites, I was wondering if anyone had any experience or input as to which is better or even some sort of further discussion.
Thanks,
Matt
