Growing dill and caraway for seed - can you?

[Annemieke]

Has anyone grown these successfully? The dill leaves were nice while they lasted, I added them to my sandwiches. But the seeds don't taste very good. I harvested most of them when they were ready (black) and dry. Caraway ditto. Maybe, in the case of caraway, the tiny threads attached to them don't help, though I can't see how to get those off. 
Is it me, the year, or the (South) English climate? 
I have successfully grown coriander: the seeds smell lovely when ground, as opposed to those other two.
Thank you!

I did grow caraway for seeds one year, but I'm pretty sure it was a special variety ?from Real Seeds that was supposed to be good for this purpose? I remember they were tall scraggly plants and I didn't bother again, but it's a good idea!
