You can knead the dough by hand or machine though machine is easier because of the sticky nature of the dough. Combine 2 1/2 cups of flour, the cream, milk, eggs, yeast, salt, and sugar in the bowl of a food processor. Process until a ball of dough that rides around the blade is formed, about 45 seconds. Dough will be very sticky. If the dough seems more batter like then add a little more flour until the desired consistency is achieved. Please resist the temptation to add too much flour because the dough must be sticky and a little difficult to handle.
