Black whole onions — Cebolla Negra — unflawed. Don't miss this incredibly delicious eat—delicate, extravagant and filled with umami. Black fermented onion, produced in the Córdoba area of Spain, and is made through a natural fermentation process. It is prepared from the manufacturer's own breeding of fresh onions, in which the black onions are obtained through a controlled temperature, humidity and over an estimated period of time. No preservatives or additives have been added. This achieves a characteristic and delicate taste of sweetness with licorice notes, a little sourness and a piquant taste of natural onion. The consistency is soft and has a creamy texture (like a soft licorice boat) The onions have a sea of uses; in a stirred mayo, in soups, sauces, as a little snack for your tapas table, for your drink — or just because, you can't leave them alone. Store dry, not too hot and preferably refrigerated. They can be frozen to increase shelf life.
