Steak - REAL steak. I was almost 40 before I truly found out.
When I was a kid, we got cubed steak, bullshit steak, and 'I can't believe this shit is actually meat' steak, So as an adult, I ain't know no better.
In 2016, I had a roommate and Acme Supermarket had a steak sale, so I went up there with like $150 and bought a bunch of steak, what I thought was good steak.
One day in the spring, We're sitting around watching The NBA playoffs and I throw a steak on the grill and asked him if he wanted one, he said yes so I threw two on. I seasoned it and cooked it, gave him one and I ate one.
He took one bite, set his on the counter and said, I'll be back
He came back with what I now know is filet mignon. That shit was butterflied and he seasoned it and threw it on the grill. Flipped it over, threw a pat of butter on the back side, threw it on a plate and gave it to me.
I cut into that shit, saw that pink and was like, "Naw, throw my shit back on the grill. This shit ain't done. This shit mooing still."
He said, "Naw, dude, trust me. I wouldn't bullshit you."
I bit into that shit like Simba with the bug on Lion King, but better...
That shit was good, good good. Blew my fucking mind good. I had no idea you weren't supposed to burn the fuck out of steak. I had no idea of anything other than medium well and well done. I had no idea what a good cut of meat was.
All that meat was in the freezer was 'fajita meat' from that point forward. I was filet mignon from that day on

Also, I was much older than I should have been before I found out that the butcher at the grocery store can cut meat that's packaged at the store.
After I discovered filet mignon, I discovered that it's much cheaper if you get a whole tenderloin (between $55-80 at most stores), Give it to the butcher and tell him to cut it into filets and you can get 13 or more fillets out of that tenderloin PLUS they give you the remaining leftover pieces as ground meat - and they do it for free!
