Barm cakeA barm cake is a soft, round, flattish bread roll from North West England, traditionally leavened with barm. Bacon is often the filling for a barm cake, at home or in Lancashire cafes or bakers. Chips are also a popular filling, sold in most fish and chip shops in the North West of England and often called a chip barm. Another popular filling in the North West, particularly Bolton, is a pasty barm. In Wigan, a whole savoury pie is served in a barm cake, traditionally known locally as a Pie Barm or Slappy, and more recently as a "Wigan Kebab".
LeuconostocLeuconostoc is a genus of gram-positive bacteria, placed within the family of Lactobacillaceae. They are generally ovoid cocci often forming chains. Leuconostoc spp. are intrinsically resistant to vancomycin and are catalase-negative (which distinguishes them from staphylococci). All species within this genus are heterofermentative and are able to produce dextran from sucrose. They are generally slime-forming. Blamed for causing the 'stink' when creating a sourdough starter, some species are also capable of causing human infection.
