ABC's Lauren Stiffelman reports from London You may have heard of the pluot and the grapple, but now…the pineberry? A summer berry that looks like a white strawberry but tastes like a pineapple is going on sale in the United Kingdom this spring. The pineberry is white, covered with red seeds and has the same genetic make-up as a strawberry, but has the taste and smell of a pineapple. The British supermarket chain Waitrose will sell the pineberries in 45 stores across the UK for the next five weeks while they are in season. ”Designer fruit” have gained popularity in the last decade, and in the United States alone it has become a $100 million business. These fruits are a product of cross-breeding, not genetic engineering. The pineberry originated in South America as a wild variety of strawberry, and seven years ago Dutch farmers began growing the fruit commercially in glasshouses. The fruit turns from green to white with dark red seeds when ripe. The pineberries will sell for £2.99 ($4.50) per 4.5oz bag until April 13 and then sell for £3.99 ($6.00).
