Sous Vide Rack of Lamb

Rack of lamb isn't cheap, so it's understandable that cooking it can be even more nerve-wracking than cooking a pricey steak. What's more, lamb tends to be leaner and smaller than a steak, which means that it's even more susceptible to accidental overcooking. All of this makes it an ideal candidate for cooking sous vide, which makes overcooking nearly impossible and perfectly edge-to-edge medium-rare results the norm.
