Export hopes for urine-boiled eggs
Traditional chefs in China are hoping their local speciality - spring eggs hardboiled in boys' urine - will catch on worldwide.
The dish has been a local delicacy in Dongyang, Zhejiang province, eastern China, for thousands of years.
Now culture officials want to spread the gospel about the recipe which they hope to export to other countries.
"The urine is gathered from local schools and the very best comes from boys under 10 years old. They pee in buckets and we collect it fresh every day," explained chef Lu Ming.
Then the eggs - which have official cultural significance status - are boiled in the urine, first with their shells on and then with them off for a day and a night before they're 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."
