Tesco’s (two stars from five) offering had the biggest chunks of meat and fat, but was let down by a dry texture and unpleasant fibrous feel when chewing.

The chorizo from Asda (three stars) boasted succulent meat, but the fat was rubbery. Morrisons’ (two stars) had more of a garlic hit and the meat parts outnumbered the fat. However, several slices were sporting gaping holes, which looked unappetising.

The skimpiest slices came courtesy of Waitrose (three stars) and its satisfyingly chewy texture was spoiled by excessive use of paprika and flavouring. There was a nice balance of paprika and flavouring on Sainsbury's (four stars), though, which made this the best chorizo on offer by far.
