Which do you prefer to add to your sandwich, is it salad cream or mayo? For me it's definitely salad cream (has to be Heinz) as it has a tangy flavour and feels light compared to mayo which I think is heavy, with not much flavour just eggy really. A lot of sandwich shops / cafes still don't have salad cream, such as today the guy making my chicken and salad sandwich said I was the only regular customer who asks for salad cream as 'everyone' prefers mayo! As an aside can anyone tell me if I can buy little individual packets of salad cream anywhere to put in my handbag so I can stop hassling sandwich guy? So I need this very important question answered please!
