I brought chuck like people recommended, ground it through a coarse plate.
Mixed the meat together with some salt and pepper. Fried it on the skillet with a sprinkling of seasoning salt each side.
Meat came out well-seasoned but the patty itself still had that "day-old, leftover reheated" hamburger taste to it that you find, for example, in a Mcdonalds or Burger King burger when it goes cold or you forget to eat that day and then reheat in the microwave and consume the next day. Just not the same taste as the hamburger when it is consumed after it is freshly cooked.
I think the culprit may have been the age/freshness of the chuck roast itself. (Which may have been sitting in our deep freezer going on months.)
In your opinion, does the age of the chuck roast affect the final freshness quality of the burger, despite being ground, cooked and consumed all in one day?
