How to make Rēwena Parāoa for Matariki By Space 7

First we heated the milk and added vinegar. Then we stirred the mixture until lumps formed. Why did this change happen? Next we poured the mixture into a sieve and the whey drained but the curds remained. After that we drained the curds onto a paper towel and when we pushed all the lumps together it becomes casein. Finally we moulded the casein into a shape.

Before beginning, a Rēwena&nbsp;bug is needed.

1/2 cup of high grade flour 1 Tbsp of sugar 1/2 cup of potato water 1/2 cup of Rēwena bug little extra warm water

1) Mix together 1/2 cup of flour with 1 Tbsp of sugar and 1/2 cup of warm water.

3) Whisk it all together in the jar until there are no lumps.

4) Cover and place somewhere warm overnight.

Finally serve and eat the soup with Rēwena bread.

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

After that heat the non stick pan as grease with a small amount of butter.

Spoon the mixture in tablespoons onto the hot pan.

Turn the pikelets over when bubbles appear.

Leave cooking for several hours until vegetables become soft. Turn off and leave until cool.

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

How do we grow and look after the Rēwena bug?

What happens when we mix milk and vinegar together?

3) Measure out 3 tablespoons of vinegar into the milk.

4) Stir the vinegar and milk together until lumps form. The lumps are called curds.

After that ladle the cooled jelly into the patty cases and place in a fridge to set overnight.

First:&nbsp;What is a Rēwena bug? Second: The Rēwena bug is a living culture and needs to be fed. Third: No two Rēwena bugs are alike. They might look the same, but each one behaves differently in baking. Fourth: Making Rēwena bread takes perseverance and patience.

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.

4x cups of high grade flour 1 Tbsp of sugar 2x cups of the Rēwena bug 1x cup of warm water

3) Make a well in the centre and add 1 warm cup of water.

5) Mix everything together using a large mixing tool.

Next add the wet ingredients to the dry ingredients and stir well.

Before beginning, cover the tables with newspaper and sort the vegetables into root vegetables and green vegetables. Set out the peelers, knives and chopping boards.

Overall we thought that our pikelets were delicious because we made them We enjoyed watching the little bubbles form to know that it is time to flip them over.

By making pikelets, we are Space 7 Scientists. By applying heat, we changed our liquid mixture into a solid. The heat also causes a chemical reaction between the raising&nbsp;agent, such as baking powder and an acidic ingredient, such as milk. This reaction produces tiny bubbles of carbon dioxide gas. The bubble form throughout the pikelet, and are trapped as the batter cooks and becomes firm. We then get a light and fluffy pikelet full of tiny air bubbles.&nbsp;

If we could make our own Rēwena bug. How much time our Rēwena bug needed to be ready for baking. If there was a way to find out if the Rēwena bug was ready for baking. Why we needed a Rēwena bug for our bread dough. What would happen if we did not add our Rēwena bug to the bread dough mixture. What would happen if we did not cover the baked bread with a damp cloth. What would happen if we left the Rēwena bug in the fridge. If a Rēwena bug could blow the lid off the jar. What would happen if we used taewa, Māori potatoes.

6) Tip the curds onto a paper towel and drain.

Next heat together all the vegetables in a large crockpot with stock, water and salt.

What would happen if we heated the curds? What would happen if we used cold milk? What would happen if we used lemon juice instead of vinegar? Was this a physical change or a chemical change?

We started with a liquid and it changed into a solid. We heated the milk and added vinegar which is a type of acid. A chemical change happened. Casein is formed from the chemical in the milk when it is heated. Casein feels like plastic but can be eaten.

Overall we thought that our vegetable soup was healthy because our vegetable soup was loaded with vegetables from our school garden that we had grown ourselves. We had&nbsp;carrots, potatoes, onions, garlic, kumera and parsnip that grew under the ground. We had tomatoes,&nbsp;celery,&nbsp;green beans&nbsp;and broccoli that grew above the ground. Our vegetable soup was low in calories, so was healthier for you. Our vegetable soup was high in&nbsp;fibre, so you stay full long after you eat it. Our vegetable soup was delicious and we were proud to share it with our families.

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.

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

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

Overall we thought that our jelly was delicious. But our jelly was loaded in sugar and so we could only eat a little bit.

By making jelly, we are Space 7 Scientists. We watched the jelly from the packet dissolve as we added it to the hot water. We talked about bonds breaking down, and how they reform as the jelly cools making it set. This&nbsp;is because of a protein called&nbsp;collagen&nbsp;which is found in our bodies. Jelly contains&nbsp;gelatin, which is made from collagen which comes from animal bones and skin. When the gelatin is heated by mixing it with the boiling water the protein fibers unravel and come apart, so the jelly from the packet dissolves. As the jelly cools the fibers coil up again trapping water between them, which makes the jelly set.

The Rēwena bug is a potato bread dough starter. The Rēwena bug has the science name of Lactobacillus. The Rēwena bug has to be fed with flour, sugar and potato water because the bug is a living fermented culture. The Rēwena bug needs a warm habitat to grow. 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. Rēwena Parāoa is made with a live Rēwena bug grown from flour, sugar and potato water. Rēwena Parāoa is better for our bodies because the naturally bubbling acids and long fermentation help to break down the proteins and gluten in the flour. Rēwena Parāoa is more digestible and easier for our bodies to absorb.

Then open one packet of jelly crystals and pour the crystals into the boiling water.

First peel, chop and dice the root vegetables.

By making soup, we are Space 7 Scientists. We grew our own vegetables for our soup so we know where and how vegetables grow. We compared how the texture of vegetables changed throughout the cooking process. When we started our vegetables were hard. But after cooking for a long time they turned soft and mushy.

When warmed milk and vinegar are mixed together, it causes a chemical change that can be seen by the curdling milk. Heat speeds up the change. The liquid curdles as the milk proteins form together to create lumps. The acid causes the milk proteins to unwind and unfold in a process called protein denaturing.
