Although I didn't have ready-made Cajun seasoning, I do have a lot of spices in my store cupboard, so I googled it and found this recipe. I pretty much followed the recipe, except I didn't have any onion powder/granules, so simply left that out, and I used less salt.
It worked well in the jambalaya recipe, giving it a warm heat without being too spicy. Perfect for a chilly Autumnal evening!
(NB: I used more chorizo sausage than the recipe said because chorizo sausage rarely comes in packs of 75g and I wasn't going to waste it. And, I love chorizo. Nom nom nom. I also used about 500ml chicken stock.)
All in all, a fairly simple, hearty, warming dish. And one that could be easily doubled or tripled if you are entertaining friends. I will definitely make this again!
