Instructions
How to make the Béchamel:
Mill the porcini to a fine powder: 15 seconds, speed 10. Reserve.
Do not wash the bowl, add the 150 g butter and the onion: Varoma, 3 minutes, speed 4.
Add the flour: 100ºC, 3 minutes, speed 2.
Add the milk, the nutmeg, a few twists of the pepper milll and the salt: 10 seconds, speed 6.
Add the porcini powder: Varoma, 7 minutes, speed 4.
Pour the mixture in the piping bags and close tightly, leave in the fridge overnight (or for a minimum of 8-10 hours), overnight is best really (and usually more convenient).
How to fry:
Whisk the egg on a deep plate and place the breadcrumbs in another plate.
Snip the end of the piping bag and squeeze to get a few sausages onto the egg plate then cut them to your desired size, think that you ideally want to get 2-3 bites out of them, not more.
Heat up a good amount of olive oil in a frying pan and fry the croquetas over a moderate heat, turning them until they are golden all over. It won't take long.
