Agreed, lol. For me, it's hamburgers. I've made hundreds (thousands?) over the years but I'm still very hit-and-miss at it. Sometimes they turn out good, and other times they turn out rubbery or undercooked. Everything else I can cook with pretty good consistency, but burgers are my kryptonite.

Never messed up a Beyond Burger or Impossible Burger though, lol. Those are pretty idiot-proof, at least.
