Fresh oysters on ice

Fresh oysters served on ice, a classic presentation that preserves the flavor and texture of the sea.

About this subject

Oysters are bivalve mollusks highly prized in world cuisine, often served raw on a bed of ice. This technique is not merely aesthetic: ice keeps the temperature low, ensuring food safety and enhancing the perception of freshness. In Brazil, oyster farming has grown significantly, especially in Florianópolis, Santa Catarina, where the native Crassostrea brasiliensis and the Japanese Crassostrea gigas are cultivated in marine farms. The city is known as the national oyster capital, hosting festivals like the Festa da Ostra in Ribeirão da Ilha. Eating raw oysters requires careful sourcing: animals from clean, certified waters reduce contamination risks. Oysters are rich in zinc, protein, and omega 3, considered a functional food. In gastronomy, they are often paired with lemon, mignonette sauce (red wine vinegar, shallot, and pepper), or chili jelly. Dry white wines like Sauvignon Blanc or unoaked Chardonnay, and brut sparkling wines are classic pairings. Globally, regions such as Chesapeake Bay (USA), Cancale (France), and Prince Edward Island (Canada) are renowned for their oysters. Sustainability is a concern: overharvesting and pollution threaten wild stocks. Hence, preferring farmed oysters (which also filter water and benefit the ecosystem) is a conscious choice.
