With Ricotta cheese as base for this Nolen gur sondesh and a total of only 3 ingredients this is one of the easiest recipes of sandesh. No Chenna/paneer required. Just mix,cook cool and shape into sandesh.
You can try regular gur/jaggery if Nolen Gur is not available. Can also microwave. If you use the microwave, mix all the ingredients in a micro safe bowl and micro at 2 minute intervals for a total of 6 minutes.So micro for 2 minutes,stir, Micro again for 2 minutes, stir and repeat. After 6 minutes,continue to cook and stir in the microwave at 1 minute intervals for a total of 4 minutes. The mixture will start coming together. The mix will thicken as it cools. Microwaves vary in wattage, so it could take more or less time. My preferred method is on the stovetop though microwave version gives more paneer like texture.
