I've always been a huge fan of Rara chowchow too. This is the best chowchow that's served cook. Wai Wai is the king though but I prefer cooked Rara to any other chow chows in the market. Everytime my friends/family members/ relatives come from Nepal, I try to make sure they brought me some Ra-Ra for sure.  

By the way, have you ever wondered on the option of having your friends/family members shipping it from Nepal? It shouldn't be that expensive at all. Why don't you have your friends send you about 30 packets. It shouldn't cost more than 30 bucks! ( including shipping and all )
