For people living outside China eggs boiled in boys' urine may not sound like a particularly appetising recipe.But gourmet cooks and fans of the delicacy in the city of Dongyang, in the province of Zhejiang, eastern China, are now trying to convince the world to give the recipe a go.Spring eggs hard boiled in children's urine have been a treat in this part of China for thousands of years.Chef Lu Ming said the urine is gathered from local schools. He said: 'They pee in buckets and we collect it fresh every day.'The eggs, which have an official 'cultural significance' status in China, are then boiled in the urine, first with their shells on and then with them off for a day and a night before they are ready to be eaten.'The eggs are delicious and healthy. They stop fevers and can help you concentrate if you're feeling sluggish or sleepy,' said Ming. 'We are having a big export push because we want people outside China to fully appreciate the delicacy of our cuisine,' he added.In 2008 the local city declared the eggs as part of the city's cultural heritage, and there was even talk of applying for a UNESCO World Heritage status alongside already approved Asian treats like washoku, the traditional Japanese food, and kimjang, the process of making South Korea's spicy cabbage dish kimchi.The chefs were unable to explain why this year's urine was creating extra sour eggs.(dailymail.co.uk)ANN.Az
