Timur: the tingle behind Nepali achar

There is one flavour in a good jar of achar that surprises people who did not grow up with it: a light, buzzing tingle on the lips, with a citrus smell behind it. That is timur.

What is timur

Timur is the Nepali name for Sichuan pepper, the dried husk of the prickly ash. It grows on shrubs in the mid-hills and mountains, and Nepal's highland timur is prized for its strong aroma. It is not related to black pepper or chili, and it is not hot in the usual way.

The tingle

Timur contains a compound that makes your mouth buzz and go faintly numb. It is not a burn. It is closer to the fizz of a carbonated drink, or the cool tingle of mint, and it fades in a few seconds. Cooks use it to make rich food feel lighter and to add a citrus note without lemon.

Where it shows up in achar

• Lemon achar leans on timur for its bright, numbing edge.
• Mango and mixed achar use it along with chili to round off the heat.
• On its own as timur ko chhop, a pickle built almost entirely from timur.
• In the hills it is also used in meat dishes, soups, and some pickles of fermented greens.

Timur is usually added ground or lightly crushed, and a little goes a long way. Too much and it takes over the jar.

How to spot good timur

Fresh timur smells sharply of citrus the moment you open the packet; old timur smells dusty and flat. The husks should be reddish-brown and light. Buy in small amounts and keep it in an airtight jar away from light, because the aroma fades quickly once ground.

Why it makes achar different

Vinegar pickles get their edge from acid alone. Achar gets a second, stranger layer from timur: the smell of citrus and a tingle you feel rather than taste. It is one of the clearest reasons a Nepali pickle does not taste like anything else.
