Choko—Used in Mexican, Chinese, and Indonesian cooking, this delicate, pale-green, pear-shaped vegetable, which is related to the gourd family, originally came from Mexico, where it is known as chayote. When buying chokos, look for young tender ones with pale, green, almost translucent skin. The spikes on the skin should be short and soft. Chokos add a subtle flavour and an apple-like texture to any dish.
