Jambalaya and a crawfish pie and file gumbo; 'Cause tonight I’m gonna’see my ma cher amio; Pick guitar, fill fruit jar and be gay-o; Son of a gun, we’ll have big fun on the bayou.
I agree that jambalaya does not have okra as an ingredient—then again, neither does file gumbo.
But chorizo may be in either a casing or loose, while andouille is always in a casing. Of course sausage in a casing may be sliced as thinly or thickly as the cook desires, so one can find very fine jambalayas that have sausage ranging from thin slices to chunks.
For me chorizo (at least Mexican) includes chilies, while andouliie does not.
I have nothing really important to add as far as the difference between the two items in question, but I will say this about chorizo....
Best cooked with scrambled eggs and ham. My grandmother use to cook chorizo every morning for breakfast (typical mexican meal in the morning). She would could up some delicious ham, homemade beans (never canned) and mix in chorizo with scrambled eggs. She would always have chile with everything.
She also made chorizo patties rolled in a chile paste. YUM!
