Iranian chai

Persians met tea through Silk Road trade with China and made it wholly their own, centring the ritual on the samovar — a continuously heated urn, which Iranians claim to have developed independently, that keeps water ready all day. A concentrated brew steeps in a small teapot resting atop the samovar; each glass is then diluted to taste with hot water below. The result, poured into small glasses (estekan) on a tray, is offered constantly: to arriving guests, in bazaars, in the qahveh-khaneh (traditional teahouse), and throughout family life. The signature act is the sweetening. Rather than stir sugar in, many Iranians place a cube of qand between their front teeth and sip the hot tea through it, or dissolve nabat — saffron-flavoured crystallized rock sugar on a stick. To offer chai in Iran is a near-automatic reflex of hospitality, and refusing outright can seem cold; a polite 'ta'arof' back-and-forth often precedes acceptance.

How it's prepared

Water is kept hot in the samovar. A strong concentrate steeps in a teapot set on top; each glass is filled with concentrate and thinned with hot water to the drinker's strength. Brewed dark and clear, never with milk. Best served a deep amber-red — a pale glass suggests it wasn't steeped long enough.

The vessel

The estekan is a small clear glass, frequently set in a decorative saucer and sometimes rimmed with silver, presented on a tray. Its clarity displays the tea's colour, and its small size keeps each serving hot.

Its social role

Tea is the reflex of Persian hospitality — the first thing offered to any visitor and a constant of gatherings, teahouses, and negotiations. Serving it, traditionally by the host, signals welcome and care; sharing endless glasses signals unhurried company.

What accompanies it

Qand (sugar cubes) held between the teeth; nabat (saffron rock candy); dates, pastries, and sweets; often taken after meals and through the day.
