Place the first steak, soya sauce, Worcestershire, lemon juice , and garlic powder into a vacuum seal bag. Seal. Next mix the rosemary and butter and place it, and the second steak in another vacuum seal bag. Seal.
Set temperature on circulator to 131F.
When temperature of the water is 131F, add the steaks and cook for 90 minutes.
After the 90 minutes is done, remove steaks from bags. Set a frying pan to a very high heat, we are looking to brown the surface without cooking the inside of the steaks. Place the steaks in the pan and fry on both sides for approximately 90 seconds on each side,
Note: you can use any combination of steak seasoning or marinade. It's a personal choice. I prefer the soya sauce and garlic powder, it adds a great subtle flavor.
