Handed the Staff of Wizard...
I imagined a Dutch Oven cook-off to be just that. Everything cooked would have been performed in a DO.
Dressings, like salsa, guacamole, and hot-sauce etc. would be fine to add as a topping. Anything that could be considered a condiment, garnish, or Foo is fine to add later.
Anything that needs to be "cooked twice" like carnitas or stuffed pastry are walking in the gray area. Technically, both could still be performed in a Dutch Oven, but there's enough room for hoodwinking and bamboozling. <-- I'll need to consult with SoFlo Posse members about this gray area.
[ex] We will not see Dutch Oven ribs finished off on the grill, nor the smoker, nor the skillet.
I'll make a final ruling tomorrow evening.
