Rewena bread Rewena bread Rēwena parāoa (literally, "leavened bread," also spelled rewana) is a traditional Māori sourdough potato bread. Rēwena means both "bread made with potato yeast" and "the process of fermentation that causes bread to rise." The Maori word for potato, 'riwai' (sometimes spelled 'rewa'), is the root word of rēwena. Rēwena bread uses a pre-ferment starter, also called a ‘bug.’ It is created by boiling and mashing potatoes, then adding flour and sugar. Kumara, or sweet potatoes, may also be used. The mixture is then allowed to ferment from one to several days, depending on the ambient temperature and humidity.
Substance theory inverse relation is participation. Thus in the example above, just as red inheres in the apple, so the apple participates in red. Two common arguments supporting substance theory are the argument from grammar and the argument from conception. The argument from grammar uses traditional grammar to support substance theory. For example, the sentence "Snow is white" contains a grammatical subject "snow" and the predicate "is white", thereby asserting "snow is white". The argument holds that it makes no grammatical sense to speak of "whiteness" disembodied, without asserting that snow or something else "is" white. Meaningful assertions are formed by virtue
