I’m pretty sure we have blackberry jam, but I’m not much of a jam person, so I can’t say so from personal experience. Although if we have the berries, I can’t see why we wouldn’t also have the jam. Looks like blackcurrants is probably what you were thinking of, although they’re technically available in the US now.
Do you have blackberry jam? Or is it a different berry I was thinking of?
Edit: it’s blackcurrants, isn’t it?
