One more item, Jen.
Starting right away keep a detailed record of every cook. I use a hard covered journal. Some cooks use their computer. It's the details that count.
Here's what i record.
Menu item name, - Thickness, - Temperature, - Time cooked, - Outcome.
"Outcome" refers to comments or a critical evaluation of the result and reccomendation for improvement next time.
This way you will always be able to precisely replicate your successes and you will have a solid plan next time for how to improve the almost-successes.
