I found the Lloyd Grossman’s one too oily. I like Paul Newman, Seeds of Change or Marks and Spencer....I think the Marks one has the least sugar in, take a look at the Count on Us one.
I agree Loyd Grossman's sauces are too oily. I use Tesco or Asda's own. I've never really looked at the sugar content. I will next time I need a Bol sauce.
