Morrisons is again selling its £2 Giant Torres avocados, which come from Argentina and measure up to 25cm in diameter. They take nearly a year to grow and 70 per cent of the fruit is flesh.
Morrisons said the bulbous fruits are back on shelves this week, having sold out last year. The grocer has been working with grower Haracio Frias to cultivate, over 310 days, a second batch.Mr Frias has been monitoring crop conditions in order to "harvest at the optimum time, ensuring the best quality, creamy avocados", said the company.
Morrisons apparently has an "avocado expert". His name is Liam Hancock and he said of the relaunch: "The Giant Torres avocados were a huge hit with our customers last year so we’re delighted to be bringing them back.
"They are perfect for sharing or as an ingredient in meals such as avocado on toast."
The Giant Torres avocado, nicknamed the "chameleon avocado" due to its colour changing from green to black as it ripens, is known for its high calcium content and soft, generous fruit.
Earlier this summer, US consumers were going wild for "long-neck avocados".
The huge fruit grows to around 18 inches long and also weighs as much as a kilogram, four times that of more common varieties found in supermarkets.
While longer and heavier, the viral avocados are otherwise the same their more common, rounder equivalents - glossy, green skins surround soft flesh and a hard stone. They grow at the same pace, too.
Long-neck avocados are found in Florida and ripen in August and September like any other. Miami Fruit, which specialises in rare and exotic foods, is the company responsible, and has apparently been producing them for some time.
