If you like Indian Sweets, especially if you like Bengali Sweets (the best, although I’m biased), K.C. Das is a must visit if ever in Kolkata (for the original) or at other locations in India. K.C. Das is famous for their roshogollas (a.k.a. rasgullas), but I’m partial to the Bengali classics of Payesh (similar to kheer, but better) & Sandesh.
Sweets are an integral part of Bengali culture, akin to how I see the importance cheese in France. Even beyond regional specialties, many towns have sweet specialties that can only be found there, or at least in their arguably “proper” form. (Yes, sweet snobbery is alive and well.)
Burdwan, a city about an hour north-west of Kolkata, has three specialties that I love: Sitabhog (sweetened rice flour, re-pressed into rice shape); Mihidana (think Jalebi caviar); and Langcha (eclair size Gulab Jamun!)
All I need now is to figure out how to get K.C. Das to open up in Seattle so I don’t have to wait for the next time I am in India!
