I love pickled gherkins and spent quite a while in Sainsbury's working through their range until I found one that did not list sugar in the contents. I had tried Waitrose and Budgens in vain as all theirs had sugar and too high carbs. The Sainsbury's without sugar is only 2.5 g carbs for 100 gms - I was very happy to find them. You don't need much to add delicious flavour I think - particularly with cold meat like ham or salami. But I also eat them on their own.

Happy hunting - hope you enjoy.
