I figure at least some of us, every once in a while just have that day that seems upside down. Forget a prep item, spill something in the walk in, drop a desert, bla bla bla...
I'm kind of curious to what some of your best mess ups where, and how you handled it.
For me personally I was making our bourbon blue cheese dressing one day, and my mind told me that I was making our benedictine ranch, and I put ranch seasoning in it. I laughed, told the chef, then stopped laughing once he got mad (our chef hates tossing anything, our food costs are tremendous.) The same night I spilled about a gallon of fresh made bbq sauce in the walk in, and went through it all over again. I fixed it by spending about 40 minutes on the heavy bag that night at the gym, the next day was flawless.
