found this - hope it helps! I know I have definitely frozen some a while back but could not remember if there was instructions on the packet I had so went looking for info.
i've got some in my fridge that's been there a week and i'm still quite happily eating it, as its a 'cured' food i'm surprised at the three day use by instruction!
I was prepared to leave mine in the fridge until I read the label on the packing! I suppose it is the "elf and safety" people's ruling. Cured sausages dangle about in European shops for ages and sometimes look quite revolting.
I have chorizo regulary and the majority of the time it's been in the fridge for over a week before i've finished it. I normaly cook it in with rice and pasta dishes or diced then fried and sprinkled over salads. The act of cooking it again probably kills off any nastiness.
Firstly, yes it freezes well and you don't need to cut it into pieces first. It cuts easily enough straight from the freezer.
Secondly, there are different types of chorizo, some are essentially raw (you'll find they're soft) while some have been dried/cured (they're harder)
They each have different uses and flavours (the raw ones tend to be saltier) but they should all be fine even after 10 days in the fridge. Hell, I think I've used chorizo quite happily even after longer than that.
Thanks for recent answers and ideas from angiealf and Chappers
The one I have is evidently dry cured as it is very hard but proving to be tasty with minced beef and chicken. I had trouble with the casing and found it difficult to chew but with some difficulty I have removed it today before cooking..
