Mix all ingredients, form hamburgers (make thumb indentation in center of burger to help keep burger flat when cooking) and place in sous-vide bag. Chill bags in refrigerator for approximately 10 minutes (this will help them hold their shape). Place on Shelf in Steam oven on Sous-Vide setting for 15 minutes.
Take hamburgers out of bag, wipe off excess moisture and place on oiled hot grill, griddle or fry pan and cook for 45 seconds or until seared to your liking, turn and place cheese on hamburger and cook another 45 seconds.
Prepare hamburger on Brioche Bun or bun of your choice with toppings of your choice.
Enjoy this amazing, juicy hamburger!
