I love jelly beans, but I've never tried a chocolate covered one.
I usually buy "Jelly Stones" from Home Bargains. They're made in Ireland by Aran Candy, and when I typed Aran Candy into Google it brought up the Jelly Bean Factory.
These sweets are the same really expensive sweets you can buy under the name Jelly Bean Factory, but they're the mis-shapes and oddballs that didn't quite come out the correct jelly bean shape.
The tubs contain 350g and when they have them in store, (they sell out fast) they're 99p a tub.
I buy lots of tubs when I see them.
I really love jelly beans.
