Morcilla burger. Dark blood pudding, white baps

I felt it unnecessary to subtitle this amazing burger at it may put some people off making it, but subtitled it is and so remains here.  Morcilla is the king of black puddings and my go to choice in a tapas bar.  I'm very fortunate in the area I live to have not one, but 2 amazing delis and it was in one of these that I found the genuine Spanish morcilla.  My only criticism of this burger is that I couldn't really taste the pork and if I make it again, which I surely will, I'll reduce the morcilla by half.
