Prepare your sous vide station by filling any large container with water, like a pot. Set the machine to heat the water to exacly 129 degrees for 3 hours.
Mix all the spices and other ingredients together and cover both sides of the steak. Put it in a totally sealed, high quality plastic bag, like a good ziploc. When the water hits 129 degrees, put the steak in the bad all the way to the bottom with all the air out of the bag.
After three hours, take your steak out and get rid of the bag. Pat dry and season more.
Cook the steak on high heat in a pan for 2 minutes on each side. Take out and let it cool for 5 minutes, then slice thinly.
