Cuttlefish ink croquettes.
Croquettes, usually with potatoes and ham, can also be found with squid ink.
It was the first time I tried them and I must say I was impressed.
Externally they are like all the others but if you open them (as in the second photo) you will see the difference in color and, when you taste them, in taste.
I tried these in Ibiza at the Chiringuito Restaurant in Cala Gracioneta.

Croquettes are usually enjoyed as an aperitif or as a side dish and are part, I believe, of the Spanish culinary culture of tapas.

The Spanish term tapa refers to a wide variety of typical Spanish food preparations, both savoury and sweet, consumed as appetizers or starters. Spanish tapas are prepared with ingredients related to Mediterranean food production.
Le tapas possono essere fredde, quando vengono preparate, per esempio, con le olive miste e il formaggio, o calde, con polpo e calamari fritti.
