In a large bowl, mix the cold and hot water, sugar, salt, olive oil, yeast and milk. Then slowly add the wholemeal and white flour, while constantly mixing and kneading with your hands. You may need to add a bit more flour than stated as the dough should not be wet at all.
Sprinkle your work bench with the extra flour so that it is well dusted. Cut a piece of the dough and shape with your hands to form a long log. Use the knife and cut the dough in pieces roughly 90-100g each.
Make all the pittas and lay them on trays lined with towels or baking paper. This recipe makes up to 50 individual pittas (see notes). By the time you finish with all the dough it will give them some time to rest before cooking. Rolling out all the dough took approximately 30min to do.
George turnt the heater on in the room (at 30°C) so that it was warm enough to help the dough rise. Choose a room in your house that is warm but if you feel that it is still cold, then add blankets on top of the covered bowl as well.
The recipe makes a lot of pittas so unless you consume them within a few days you may also freeze them in freezer bags for up to 3 months.
