SHOPPING TIPS

Generally sold by the dozen or half-dozen, already shucked (opened). Look for lustrous, plump, moist flesh with a pleasant fresh sea smell. Unshucked Oysters should be closed or close when tapped or gently squeezed.

STORAGE TIPS

Shucked Oysters are best eaten on the day they’re purchased. They can be refrigerated for up to 2 days, but will taste best cooked if not eaten within 24 hours, and can be frozen for up to 3 months, below -18ºC, and used in soups or sauces.Live molluscs should be consumed as soon as possible after purchase. Place in a container, cover with damp paper or cloth and keep in the warmest part of the refrigerator, usually the crisper (optimum 5ºC), ensuring that the covering remains damp.

COOKING TIPS

Average yield is 20-40% from half shell. Has a rich, iodiney flavour, low - medium oiliness and moist, soft, creamy flesh when raw, turning browny-grey when cooked. If not consumed raw, they require very little cooking, either a quick dip in hot oil (usually with a coating) or a very gentle warm through; stop cooking as soon as the edges of the meat start to curl, as overcooked they will be tough and tasteless.

COOKING METHODS

Steam, poach, deep-fry, pan-fry, stir-fry, bake, grill, barbecue, smoke, raw (sashimi), pickle.

Flavour pairings

Bacon, breadcrumbs, cream, eggs, fresh herbs, garlic, ginger, green onions, lemon, lime, mirin, pepper, soy, Tabasco, tomato, wasabi, Worcestershire sauce.

IMPORTS

Pacific Oysters are imported from New Zealand, chilled on the half-shell. Frozen, dried and smoked Oysters are also imported from many countries.
