Step by step

Prepare some beaten egg white (only a little)

Tips
Pay attention to the temperature of the oil when frying these pancakes! If they become too dark it means that the oil is too hot and that the filling will remain undercooked. Take care to start with an oil temperature of 150°C and bear in mind that as you gradually add the pancakes to the oil, the latter will reduce in temperature by a few degrees.
Trivia
The filling of the first original fried crispy pancake marketed in Italy was just cheese. Only later, given the product’s success, did the company that made them expand the range with other types of fillings.
