Harking back to dairy, for a moment. Here's another example of that dairy produce that doesn't exist.
I recently found an online source for this.
The Chinese reads 北京蓝 (běi jīng lán)*, which means Beijing Blue. Despite the name, it is made in Xinjiang, China's westernmost province, about as far as you can get from Beijing and still be in China.
According to the description listed, it is made from cow's (sheeps) milk! I'm betting on the sheep. The area is known for sheep and not for cattle.
I haven't ordered it yet. It takes days to get here and it is over 35℃ heading to 40℃. I will order when it cools down - if it ever does!
*This name is now proving problematic as Beijing blue is also the local slang for Beijing's chronic pollution problem.
