Rēwena paraoa

Rēwena bread or Māori bread is a type of sourdough bread from New Zealand. The bread is leavened with a fermented potato starter. It originated amongst the Māori people and is closely associated with Māori cuisine. Rēwena is the direct transliteration of the word 'leaven' referring to the biological leavening ingredient used as a raising agent. Parāoa is the direct transliteration of the word 'flour' which also functioned to refer to bread or dough. Another example of bread developed by the Māori people of New Zealand is parāoa parai (literally 'flour fried').
