  • Abalone

    Abalone is a name given to several different species of sea snail. It’s hard to give an exact number because not everyone agrees on the definitions, but there are anything between 30 to over 200 species, ranging in size from small to very large.

    The name “abalone” comes originally from the Californian Rumsen language via Spanish. The final E is pronounced, so it’s “a-ba-lo-nĂ©”, not “abba-lone”.

    Abalone are particularly prized in East and South East Asian cuisine. They were once considered a luxury item in Chinese banquets along similar lines to shark fin soup and bird’s nest soup. In Korea they were often presented to the King.

    Nowadays, with the introduction of commercial farming, abalone are more popular. One Western Australian company has set up what it describes as an abalone ranch – an artificial reef consisting of 5,000 concrete blocks weighing 900kg each. The abalone are seeded from an onshore hatchery, taken out to the reef and then left to their own devices.

    In North America evidence of abalone consumption along the Californian coast has been dated back to 12,000 years ago. These days you can find abalone on Californian pizzas!

    Abalone are also sought after for their shells, the inner surface of which is covered with a particularly iridescent nacre (mother-of-pearl) that’s used in jewellery, button-making and as inlay in furniture and musical instruments.

  • Albacore

    An albacore (Thunnus alalunga)
    The albacore is a species of tuna found in all three of the world’s major oceans as well as the Mediterranean Sea.

    It’s a popular source of tuna for canning – the history of tuna canning goes back to 1903 when 700 cases of albacore were experimentally canned.

    In the US it’s the only species that can legally be described as “white meat tuna”. The canning industry use this phrase to distinguish albacore meat from other tuna species.

    It’s also known as longfin tuna. This is because of the long pectoral fin running down its side, for up to 30% of the total length of the fish.

    Like all fish it accumulates methylmercury over time, but as it’s an apex predator (at the top of the food chain) it does so to a greater extent than most fish species. Although the human body does naturally break methylmercury down over time, it takes over a year to do so.

    Albacore caught individually by pole is reckoned to be the most sustainable form of tuna, so look out for it when shopping.
