First, mix gently together the beef, salt, and pepper.
Now, dived into 2 patties (indent the middle of patties so does not rise when cooking).
Next, place butter in a pan on medium heat. When the butter starts to bubble gently swirl the pan for a minute until smells nutty (see video above).
Now, add the burgers and cook 2 minutes each side (do not move burgers except to flip so you get a great burger crust).
Finally, spoon butter over both burgers for 20-30 seconds. Then take the burgers out of pan and assemble!
