So... I finally bought a jar of nettle jelly, which I smeared on crackers and enjoyed with a piece of Cornish Yarg (the one wrapped in nettles).

It's not the most mind-blowing flavour in the world, but it has a nice, subtle, vaguely herby taste that goes very well with the Yarg. It also complements Lancashire crumbly cheese very well.

It would probably be completely lost if used to accompany a strong cheese (like the Evil Blue Cheese of Satan, for example), but seems to go very nicely with mild cheeses, and those of a herby disposition.

And it didn't sting my tongue!

I must admit to a certain degree of disappointment on that score...
