Don't worry. The Guardian is famous for being (a) trendy (b) esoteric and (c) lefty.
Trendy - there'll always be the "latest" there, so nduja (which can be found in supermarkets in the UK) and pomegranate molasses (ibid) were clear entries. Strozzapretti may (just may) have appeared on Pasta Grannies.
Nduja, apparently, is a corruption of the French "andouille", although slightly different.
Esoteric - you're quite likely to get articles lamenting the lack of Vegan options on the Scilly Isles, how to make the perfect nettle soup or the huge popularity of apple and ricotta tart with basil leaves. They've got some good writers, but others who live in another galaxy.
Lefty - it always used to be acceptable "lefty". I had a subscription for years, but when they openly began supporting Hugo Chavez, that was IT!
