In a large bowl mix warm water and sugar.
Scatter the yeast over your water and sugar mixture. Let stand to foam for 5 minutes.
Melt the butter and make sure it's warm but not hot. Add it to the yeast mixture.
In a second bowl mix together white and wholemeal flour. Then add onto the yeast mixture.
Make a small well in the flour and pour in the salt, keeping it separate from the yeast
Mix all the ingredients together with a fork until a rough dough is formed.
Turn the dough out onto a floured surface and knead for 7-9 minutes until the dough holds its shape. To test that, press it gently with your finger. If the dough springs back, it's ready.
Shape the dough into a ball and place into an oiled bowl to rise. Leave to rise for an hour or until doubled in size.
In the meantime, line a baking tray with baking paper.
When the rise is finished, turn the dough onto a floured surface and knock it back with your fists to flatten it.
Divide the dough into 8 equal parts.
Use a rolling pin (or hands) to roll each part into a long strip (about 1.5 cm wide and 25cm long). Take the ends end cross one over the other and do the same again, and fold the whole twist over the curve of the strip to create the pretzel shape (watch the video to see this - coming soon).
