Forcing/blanching for an early crop

I tried covering some dandelions to blanch them, but it was when I was living in Grimsby and it was so windy all the time that I just couldn't keep them covered. Every time I went outside, the cover would be halfway down the garden!

I think I could fancy forcing rhubarb if I had a big enough garden to have multiple rhubarb plants and allow some to be forced, some to rest and some to be used for regular harvesting every year. Hmm, maybe of multiple different varieties... I do like rhubarb! I don't think I've ever eaten forced rhubarb before though, which is probably a bit shameful as a Yorkshirewoman.
