Fresh ground chuck and sirloin. Yup we took $6 worth of steaks and food processed them up.
As per Alton Browns directions. Yes I know, we are addicted to AB. But he really does make good eats.
Twas the juiciest, best tasting burger I have ever made. And I have enough left over for lunch tomorrow.
Trick was to grind up a little of the fat from the chuck. At least I know there was no strange beef parts in it. (you would be surprised how much meat you can get from a cows vagina 😉 )
