Having used cooking chorizo from Tesco, Marks and Spencers and Sainsbury, I much prefer using the chorizo from Tesco or Marks and Spencers.
The main issue I have with the Sainsbury’s chorizo is that it comes in little sausages. From the other two stores, you get four large chorizo sausages, whereas from Sainsbury you get twelve small sausages, though from a weight perspective you get roughly the same amount of sausage.
So for the majority of dishes I use chorizo in, the small sausages are a bit annoying to slice. They also seem to be a little more salty than the other two.
However I suspect if you cooked them whole with red wine, then it would a really nice chorizo frito al vino.
