Oyster

What Is İstiridye (Oyster)?

İstiridye, or oyster, is a bivalve mollusk known for its rough, irregular shell. The flat oyster (Ostrea edulis) is the native species of European coasts; in Türkiye it is found as both wild and farmed oyster.

Its flesh is soft, has an intense sea aroma, and is mildly salty; it is most often consumed raw, with its own liquid and lemon, though it can also be cooked.

Nutritional Values of İstiridye

100 grams of raw oyster contains approximately 51 kcal of energy and around 6 g of protein; it is quite low in calories. It is one of the foods known to be richest in zinc, and it is also extremely high in vitamin B12.

What Are the Benefits of İstiridye?

With its very high zinc and vitamin B12 content, oyster is a nutrient-dense seafood product that can be considered as part of a balanced diet.

This information is general; oyster is a food, not a substitute for medical treatment. Raw oyster consumption may pose a risk for people with weakened immunity, pregnant women, and children; cooked consumption is recommended for these groups.

How to Choose İstiridye?

In live oysters, the shell should be tightly closed or should close when touched lightly; oysters that stay open should not be consumed.

• The shell should feel heavy and moist; empty/light-feeling ones should not be chosen.
• It should have a fresh sea smell, not a sharp/ammonia odor.
• Oysters with broken or cracked shells should be discarded.

How to Store İstiridye?

Live oysters can be stored in the refrigerator under a moist cloth, with the closed side of the shell facing down, for 1-2 days; they should not be kept in a sealed, airless bag, because oysters need to breathe to stay alive.

Using İstiridye in the Kitchen

Oyster is most often served raw, with its own liquid and fresh lemon; it can also be consumed grilled, baked, or cooked in a casserole.

How Is Raw İstiridye Opened and Served?

The oyster is carefully opened from the hinge with a special knife, keeping the liquid and flesh in the lower half of the shell, and served on ice with lemon slices.

Baked İstiridye

Opened oysters are topped with a butter-garlic mixture or grated cheese and briefly baked (a few minutes) to warm them.

Which Recipes Use İstiridye?
