re: Gumbo calculator....Is there one?

I am assuming this is a chicken or duck based gumbo. How big of a stock pot do you have for this gumbo? If you don't have a single one to fit the crowd you may have to do it with several to make a sufficient quantity to serve the masses. Another question that crossed my mind is simple. Do you have crawfish boiling pot? A large batch of roux in a 5qt cast iron dutch oven would suffice, then transferring it to the big pot to combine with the trinity. Make and refrigerate/freeze the stock before hand, and just defrost it earlier in the day of the party.
