I did live in a house with an airing cupboard which did work. However, I have a breadmaker and make the dough ready to shape into pitta bread pieces but how do I make it rise as I don’t have an airing cupboard.
Use your oven. If you wish, turn the oven on at its lowest temperature for about 10 minutes before you want to rise your dough. Then turn it off and place your dough inside.
Another trick is to add a pan of warm water to the bottom of your oven while the dough rises -- this increases the humidity which may help with rising.
