3 days ago I got a denver steak, the first day I cooked two slices medium rare but the steak had a pungent egg after taste. I thought maybe it was because the butter burned when I was searing it. So I tried again yesterday, 1min sear both sides without throwing butter over it. Then in the oven for 13 minutes, this time I cooked it to medium. But that nasty flavor was still there. I let my family member have a taste and they said it tastes like tainted meat. He thought I was crazy when I said it tasted like hamburger and eggs. But when he tried it he agreed and said it tastes like the meat went bad. I Didn't buy this steak, It was given to me from someone. The sell by date was the same date when I got it. I think the steak may of been left out to dethaw, then it was refrozen after bacteria started growing. I'm guessing that's what happen because I've had a cut of steak taste so disgusting. I've never ate tainted meat either so Idk if that rotten egg after taste is really from the meat. Anyone know if the denver steak just tastes like shit, or if it was tainted.
