Cut the pumpkin into chunks and cook it in a non-stick pan with chopped shallot, rosemary and a drizzle of extra virgin olive oil. Purée the cooked pumpkin, transfer it to a bowl and add a pinch of salt, beaten eggs, the flour and yeast, sifted, 50 grams of finely grated Grana Padano and 50 ml of milk, stirring together well until the mixture is soft and creamy.
