Place in a greased bowl and cover with a tea towel. Leave for an hour to double in size.
Roll the dough out on a well floured board to 3 cm thick. Cut round circles of about 8cm. If you want a hole in the middle then use a smaller cutter to remove the centre.

Pour 4cm of oil into a deep frying pan or pot. Heat the oil to 180 Celsius.
