Sous Vide Satsuma A5 Wagyu to Perfection!

True confession: I am a closet sous vider. I come from the last of the old guard that rejected sous vide in favor of more classical techniques. I was first exposed to sous viding when I did a stage for Joel Robuchon in Paris in 1996. He had a pork belly dish I vividly remember, the ultimate Petit salé aux lentilles, a melt in your mouth dish of cured pork belly served over creamy lentils. Petit salé is far too bourgeois for most diners of a three star Michelin restaurant and I am convinced the dish was not actually on the menu but there only for gastronomic regulars in the know. Each morning at Robuchon a plastic tub was filled with warm water and a strange device attached. The machine gently hummed while vacuum-packed bags of cured pork belly were lowered in. All throughout prep and service, the machine circulated water heated to a precise temperature around the packets.  It felt like Christmas whenever someone ordered it. Time stopped. Everyone’s attention was fixated on the opening of that one single package and I always wondered who was on the other side of the swinging kitchen doors eating it. Since then, every “modern” kitchen I have worked in had at least one such circulator.
