In a jug, combine the warm water, sugar and active dry yeast.
Set aside until foamy.
Now, in a large bowl, mix the flour and salt.
Add the yeast mixture, milk and melted butter to the flour.
Mix until it forms into a dough and transfers to a floured surface and knead until springy.
Form into a ball and place back in the bowl. Cover and set aside in a warm space for about one hour or until it doubles in size.
Preheat oven to 180c.
Grease a 9-inch spring-form pan, and line bottom with baking paper; grease the paper, then set aside.
Transfer the dough back to a floured surface and knead again for a few minutes
Roll the dough into a very thin rectangle.
Spread a thin layer of chilli oil and harissa mix on top of the dough, but leave a little space around the edges.
Scatter the olives over the top.
Starting at the long edge, roll slowly and tightly into a log. Press it closed.
Now carefully (it’s messy!), cut the dough in half along the length (so you get two long strips).
To form the loaf - Cross the two halves with the layers facing up.
Continue to lay the left piece over the right until the dough is tightly twisted.
Pinch both ends together.
Now roll the braid into a tight circle (like a snail) and press the ends together
Carefully transfer to the baking tin and cover and allow it to double in size.
Once risen, pop in the oven and bake for 35 minutes.
Allow to cool a little before eating.
