PREPARATION
Place the flour in a bowel. Next, whisk together the egg, egg yolk, heavy whipping cream, melted butter, oil and milk as well as the salt. Make a well in the middle of the four and pour the liquids into the well; combine all ingredients until the dough is smooth. Let the dough rest for 30 minutes. Once rested, roll the dough out thinly on a flour-coated surface and fill with fruit jam from South Tyrol. Fry the doughnuts in hot oil, pull them out and place on kitchen paper towels to drain the excess oil. Sprinkle with powdered sugar and serve immediately.
