To prepare these delicious appetizers you must first clean the sardines: so wash them and gently remove first the head, then the "fin" on the back and finally the internal bone. To remove the inner bone without splitting the sardine into two fillets, and opening the sardine like a book, cut the belly of the fish with your finger, starting with the head. Holding the tail tightly, which will ensure that the sardine stays together, proceed gently up to 1 cm from the tail.
Once the sardines are ready, dip them first in beaten egg and then in breadcrumbs.
At this point you can choose which type of cooking you want to use: more delicious if fried, or lighter and healthier if baked. If you choose to fry them, heat plenty of oil in a small pan and, when hot, fry the sardines in it. When they are golden, place them on a sheet of absorbent paper and salt.
If you choose to bake them in the oven, preheat the oven to 180°C (356°F). Place the anchovy fillets on a baking tray covered with baking paper, drizzle with a little oil and add a pinch of salt. Cook in the oven for 5-10 minutes, or until the sardines are golden brown.
Finally, enjoy them hot with a squeeze of lemon juice and enjoy!
