When life gives you lemons, make lemon chicken

When in London for the Lunar New Year week, I met an old friend in Chinatown: lemon chicken.

If you are a foreigner in China, you are no doubt nodding your head. If you are a mainland Chinese, however, you may be scratching yours in confusion. Lemon chicken, you see, is a staple of Chinatown restaurants around the world.

I've never seen it in China, though, despite having lived in Beijing for almost seven years.
