Not all strawberry varieties taste the same, no matter how well you grow them. It's taken me years to track down shop varieties with consistently beautiful flavour and now I have two, both available this year and last, both of which go on for weeks. Variety is always marked on the pack here. I wouldn't buy, or even pick, unnamed varieties. There are far too many which produce huge crops with no flavour, as with tomatoes. Once you've bought your strawbs, it's either today, tomorrow or the bin (or jam). I've never eaten a strawberry that's been frozen. Maybe they make nice juice for ice cream. Raspberries out of the freezer taste lovely, but don't expect much in the way of texture.

And why does Bonne Maman strawberry jam taste so bloody good...
