Dissolve your sugar into the warm water and add your yeast (if using active dry or fresh) - leave to bloom for 5 minutes. Instant dry yeast can be added directly into the flour and does not need activating
Mix your flour and salt
Once your yeast mixture has bloomed, add it to the flour along with your yogurt and olive oil
Mix to combine and knead for 5-7 mins until you can form a smooth dough ball. The dough ball should have the slightest "stick" to it
Place into a greased bowl and cover with a damp towel, leave to rise for 1-1.5 hours or until doubled in size. You can also refrigerate the dough for a minimum of 12 hours up to 48 hours
Once risen, turn out onto a floured surface and portion into 8 doughballs, transfer these to a baking tray
Cover the tray with a damp towel/cling film or a lid and rest for another 30 minutes. If using dough from the fridge, allow to rest for 1 hour
Roll each piece of dough into your desired shape using a rolling pin or by hand
