ostión

Ostión refers to a type of oyster, often specifically a larger or more mature specimen. In culinary contexts, it typically denotes oysters that are suitable for consumption, distinguishing them from smaller, younger oysters that might be used for different purposes. The term is commonly used in Spanish-speaking regions.

Ostiones are bivalve mollusks belonging to the family Ostreidae. They are known for their rough, irregular shells and their succulent meat. These oysters are filter feeders, drawing in water and straining out plankton and other small organic particles. This process contributes to their flavor, which can vary depending on their environment and diet, often described as briny, sweet, or mineral-like.

Commercially, ostiones are harvested from both wild populations and cultivated beds. They are appreciated globally as a delicacy and are consumed raw, cooked, or incorporated into various dishes. Their nutritional profile includes high levels of zinc, vitamin B12, and omega-3 fatty acids. The term "ostión" emphasizes the oyster's readiness for consumption, often implying a size and maturity that makes it ideal for culinary applications.
