/ck/ - Food & Cooking

today I'm trying my hand at making gumbo.
I'm using whitefish and andouille sausage as the meat. I might be able to find some shrimp in the freezer here but I can't afford to go buy shrimp.
the veggies I bought to go in are eggplant, okra, little gold potatoes, portobello mushroom caps, and then some brown rice to fill.

what spices should I use? I have tomato paste and chicken broth as my base.
any other vegetables I should go get before I start?

tl;dr how does /ck/ make gumbo?
