Shocked with the concept of urine-soaked eggs? Don't be: it's a popular springtime snack for residents of China's coastal Zhejiang province.

Young boys, preferably below the age of 10, douse the eggs with urine collected from primary school toilets.

Popularly known as "virgin boy eggs", it takes nearly an entire day to marinade them. The raw eggs are soaked and then boiled in a pot of wee. Gradually, the shells of the hard-boiled eggs crack allowing the egg white to absorb the urine for hours.

Fresh urine is poured in at intervals and the temperature is strictly controlled to keep the eggs from overcooking.

This snack is believed to have medicinal properties, allegedly easing aches in waists, legs and joints, increasing stamina and immunity from heatstroke.
