The story
Sichuan pepper was China's main hot spice long before chillies arrived from the Americas, and it was mixed into the plaster of Han palace rooms for its scent. The tingle it leaves on the tongue is half of the flavour called málà.
Planting
Sun or light shade and any soil that drains. It is hardy and unfussy.
Growing
Prune in winter to keep the middle open. A single plant will usually fruit.
Harvest and use
Pick the red husks in autumn as they split, dry them, and shake out the gritty black seeds. Toast and grind the husks.
What to watch for
Thorns. Keep it away from citrus orchards, as it can carry citrus diseases.
