Thanks for the (multiple) definitieions!
I suppose in the states the word 'buns' has multiple uses as well....
Either way... dough + a bit of lard or other fat= excellent. Ive had the irish version with currants before, very nice.
oh, and regarding the issue.... is it possible that the problem isnt with your baps/buns at all, and the burger just needs more time to 'rest' after cooking?
