Funny you mention the Prudhomme Family Cookbook. At work today I was digging in another fire stations cook book cabinet and found that one, and "borrowed" it, they did't deserve it anyway. It's definitely the country food I grew up with.
I also have a series of cook books I love that goes back quite a ways, kind of a novelty, I think the author was Mercedes Vidrine from Eunice, the first was Quelche Chose Bon, then a few others, Quelch Chose Doux, Quelche Chose Pimente, and one about seafood. You could tell those old cooks were being pinned down to amounts and weren't used to thinking in terms of measurements.
