This is a marwari delicacy of moong dal vadas immersed in tangy mustard flavoured liquid. The 'kanji' or 'rai ka pani' as it is known needs to be prepared a day in advance so that all the flavours mellow down.
The vadas are added the following day. Kanji vadas are a popular snack sold on the streets throughout Rajasthan. Chukandar (beetroot) kanji is also popular and is specially prepared for the festival of Holi.
Instead of moong dal vadas, large chunks of beetroot are marinated in 'rai ka pani' or 'rai ka achaar' to give it a rich red colour. Serve plenty of kanji with the vadas so that you can enjoy a large sip of the kanji once the vadas are polished off.
