Taste the pleasure and pain
Eating real Sichuanese food is like giving your taste buds a workout, taking your tongue down to the gym to give all those latent senses some stimulation.
Taste is, indeed, a matter of senses. The taste buds respond to four different types of tastes: sweet, sour, bitter and salt.
This may sound technical but bear with me. The sensations which we enjoy when we eat our favourite dishes are, in theory, subtle combinations of these four elements.
Heat is pain. If you have ever inadvertently eaten your way through a whole green chilli you will understand. A little pain can, of course, mean a little pleasure; pain can be exciting for your taste buds.
Some experts believe eating chilli weakens the sensitivity of the taste buds; aficionados say sensitivity is actually enhanced by the heat and flavours take on a fresh quality.
Of course, it is impossible now to imagine Sichuanese food without chilli. But until the late 17th century, when the Portuguese brought chilli to China from its native South America, the Sichuan basin's millions of residents made do without.
