localfoodie, are you with Red Stick Market in Downtown Baton Rouge? New Orleans has several markets run through Loyola, which I thought Red Stick was an offshoot of.....CBD market on Julia has had chef cooking demonstrations for years.....I based Clayton Farmer's Market off their format. One of the things I altered was to have the cooking demo on site with product selected from the market.
My market box had equipment so that any visiting chefs wouldn't have to scrounge for burners, fuel etc....
The chefs I worked with did not want to compete against each other.
Amatuers would compete though.
Guest chefs would participate in festivals.
One of the ways I brought in top chefs was to make it easy on them....just showing up early on a Sat morning is a huge task for many of them that work the line Friday night, then go in and work a full Sat. I had a one say, "Julie, I love doing the demo but I fall asleep on Sat night line when I demo Sat morning".......
MTPC, have guidelines. The cooking demos will use product from the market, explain it's cross marketing. Recipes are important. Even if you have to write them, having a recipe for the homecook @ the demo is again marketing for the market and the chef.
Chef's already buying local are more apt to support you. Chef/owners especially.
Cookbook authors doing demo/signings are another option.
You have a cooking school downtown with a cafe, network with them.
ACF juniors may want to do a fundraiser at the market, just make sure they source local for what they sell.
Good Luck, Baton Rouge has a warm place in my heart.
