Put the sifted flour in a large bowl and slowly add the milk, whisking briskly as you pour.
Once you have incorporated the milk, add the egg and continue whisking until smooth. Do not over work the batter or else it will be too elastic and grainy.
Prepare the ingredients that you want to fry, cutting them into equally sized pieces. Then, dip the foods into the batter and fry them immediately so that the batter doesn’t come off.
The batter can be stored in the fridge for 1 day max.
