Make small balls of 15-20 gms each
Roll each ball on your palm to form a cylindrical shape
Coat each of them completely, with semolina or bread crumbs (I prefer using Semolina)
Follow these steps until all the croquettes are shaped
After shaping them, if you do not wish to fry them all, you can freeze them for about 2 months in your deep freezer
If you're going to freeze and use them later, always place them in an airtight container
Place a parchment paper at the bottom of the container, Place one layer of the uncooked croquettes, place another parchment sheet on top of the croquettes and only then place the other set of croquettes on top of the parchment paper
The reason why I stress on using parchement paper, is because this will keep the croquettes separated and will make it easier and less messy when, at a later stage, you have to remove the required quantity to be fried without having to remove the entire lot of croquettes
When frying frozen croquettes, always ensure that the croquettes are fully thawed and brought to room temperature. Only then fry them or else they will break in the oil
