By tablet testing, I don’t mean that I have persuaded Google, Apple and Samsung to give me examples of their portable devices. Instead, just a short thought on chewable vitamin C tablets. I picked some of these up from Tesco after picking up a cold on my holiday in Wales last month; this week Jane got another batch from Sainsburys. I know I am not taking these things for the gourmet experience but, as an aid to memory, I think the Tesco ones have the edge flavour-wise. It might be a while before I need another batch but I want to keep that in mind.
