pay to work?
You can do it for free, that is work. It's called stag-ing. (stodging). Pick a restaurant and call the chef or sous, explain your background and inquire about coming in to work pro bono. I do this on occasion, just for the opportunity to work for and see how other chefs are doing their thing.
One place that I was at, had a chef stay for a month, she worked every station for a couple of days.
There are culinary external programs available at schools as well as culinary cooking programs at cookware and gadget stores.
There is always the private lesson(s).
one) cooks normally don't make a lot of money, yes we will cook for money
two) what chef won't come over eat your food and drink your wine for a nominal fee.
Would your spouse enjoy this, or would she enjoy it more with you along her side?
(My wife can't stand being in the kitchen with me)
