How to make dough

6) Oil the container to be baked in.

7) Pour out the wet mixture onto a floured space.

8) Sprinkle on a little more flour and knead with the tool, or by hand until it looks like scone mixture.

9) Shape into a ball and add to container.

10) Oil the surface of the ball.

11) Cover and leave in a warm place, like a car, to prove for many hours.
Prove means rise and get bigger.

1) Heat the oven to 200C.

2) Place the risen dough in a hot oven for about
1 hour.

3) Check for the golden colour.
Tap and the bread should sound hollow.

4) Take out, cover with a damp cloth and then place on a rack.

5) When cold slice into pieces and serve.

Bake the Rēwena Parāoa

Serve with butter and eat with soup.
Invite families to share.

Eat the Rēwena Parāoa

What did we find out

First: What is a Rēwena bug and where did it come from?

Second: The Rēwena bug is a living fermented culture and needs to be fed. Rēwena means "bread made with potato yeast".
The Maori word for potato is 'rewa'.
The Maori people live in Aotearoa, New Zealand

Third: No two Rēwena bugs are alike.
They might look the same, but each one behaves differently in baking.

Fourth: Making Rēwena bread from the Rēwena bug takes perseverance and patience.

What did we notice

The next day our Rēwena bug had doubled in size and filled the big jar.
The smell was like vinegar.
The Rēwena bug bubbled like a hot pool.
The really bubbly Rēwena bugs made bigger bread.
The inside of the Rēwena bread had little holes.
One Rēwena bread fed two classes and our families.
A car was a good place to prove the bread.

Conclusion

The Science

The Rēwena bug is a potato bread dough starter.
The Rēwena bug has the science name of Lactobacillus.

First the Rēwena bug has to be fed with flour, sugar and potato water because the bug is a living fermented culture.

Then the Rēwena bug needs a warm habitat to grow such as a hot water cupboard.

Next the Rēwena bug acts as a natural leavening agent. The bug uses the sugar and turns this into natural yeast. The yeast is what causes the foaming and acid smelly action. The carbon dioxide gas causes the smell. The foaming action is what lightens and softens the bread dough. This action helps the bread dough to rise and get bigger.

After that the Rēwena Parāoa is made with the live Rēwena bug grown from flour, sugar and potato water.

Finally we eat the Rēwena Parāoa.

Overall the Rēwena Parāoa is better for our bodies because the naturally bubbling acids and long fermentation of the Rewena bug helps to break down the proteins and gluten in the flour. The Rēwena Parāoa is more digestible and easier for our bodies to absorb.
