The word 'karak' comes from the Hindi word for 'strong', and karak chai is indeed a powerful, flavourful drink. The tea and milk are simmered together – not just stirred in – which gives it a creamier, richer taste than ordinary tea with milk. The cardamom adds a warm, slightly floral flavour that is unique to this style of tea.
Karak chai originally came to Qatar from South Asia, brought by traders and workers over many decades. It became so popular that it is now considered a Qatari tradition in its own right. Street karak shops are busy from early morning until late at night, serving labourers, office workers, students, and families alike.
Sharing a cup of karak chai is a very common social ritual in Qatar. Friends meet for karak before work. Families drink it after dinner. If you visit someone's home, karak chai – along with dates – is almost always the first thing you are offered. It is a small cup of warmth and welcome.
