This was not as challenging as I thought it would be. Most of the recipes of the dishes we had planned to make for Mardi Gras were readily available. The only two ingredients that were somewhat harder to acquire, but not really, were frozen okra and andouille sausage. Both of these ingredients I found at Fred Meyer, though the latter was more of a fluke and I managed to snag the last package of Aidell's Andouille Style Sausage.
Because we were also cooking for toddlers (in addition to the adults), really spicy foods are frowned upon because young digestive systems simply cannot handle it. Gives 'em diaper rash. Anyhow. I substituted a smoked turkey sausage I found at Trader Joe's for the andouille. By breaking out the missing ingredients by recipe, it was easy to create a shopping list.
For example:
New Orleans rice & beans:
1 medium onion
1 green bell pepper
1 lb red kidney beans (2-3 cans)
celery ribs
1/2 lb Andouille sausage / smoked sausage
bread pudding:
1/2 gallon organic milk (4 c for the bread pudding)
1 qt heavy cream (2 c for the bread pudding, 2 c for the whiskey sauce)
day old French or white bread
langostino etouffe:
1-2 lb langostino
4 c chopped onions (if using Emeril's recipe), so roughly 2-3 onions
I did have to look up a conversion for the beans, from dried to cooked. Because we simply lacked the time, I opted for canned red beans instead of the slow cooker method.
Also, all the recipes called for Creole seasoning, which excluding the salt, I had just taken out all the traditional Creole seasoning spices and set them on the kitchen counter. Then we could just flavor by approximation.
Besides salt, black pepper, and onions, the Creole seasonings used for Fat Tuesday's dinner were: cayenne powder, garlic powder, oregano, paprika, and thyme.
