I got the impression that perhaps someone had given him a gift pack of posh oil and vinegar bottles for Christmas, and that - while he was comfortable with the others - he couldn't quite work out what to do with this one.
I've had a look in the larder, so I think tonight I am going to drizzle it into a sweetcorn chowder served up with an Italian meatball panini. Tomorrow it will be used to season a mushroom risotto.
After that I should know if I like it or not. Here is a link to its home page for the likely future date when I have finished it and thrown out the empty bottle only to realise I can't live without it and have forgotten the brand.
