Sichuan's damp air and overcast skies help explain this mountain-locked province's famed mind-blowing spicy cuisine.

In essence this is a love story. That's how Chengdu-native and food writer Shi Guanghua describes Sichuan cuisine, as we know it today. And like all classic romances, the union of Sichuan's native Chinese prickly ash and pepper, imported from South America around the end of the 17th century, via Europe, could be a challenge to anybody trying to sample it, especially the first-time round.

The taste-bud-tingling, gullet-numbing sensation has now become a metaphor for Sichuan cuisine - famed the world over for its sharp and furious kicks on the palate, threatening to set one's mouth on fire.

As for the people of mountain-locked Sichuan, where the air is damp and the skies overcast on most days, this fiery hotness in their food is a sure-shot turn-on, Shi says.

But that's only half the story. For the "hot" in Sichuan cuisine is not just the lethal punch that might send unaccustomed diners gasping and reaching for a jug of iced water. It can also be experienced in its array of subtly-defined, multi-layered, many-splendored varieties.
