Alternatively, you can try your hand at preparing the batter: mix 125 g of 00 flour, 70 g of corn starch, 350 g of water and 2 pinches of salt in a bowl until you obtain a mixture without lumps. Leave to rest for at least half an hour, then prepare very thin crepes by cooking them in a non-stick pan greased with seed oil; should be almost transparent.

For the filling, there are also versions with pork or chicken in addition to vegetables.

For frying: peanut or sunflower oil.
Instead of rice wine you can use white cooking wine, bearing in mind that the result may not be the same.
