Won't Khoa serve the purpose? Here we buy ricotta because Khoa is not available or is damn expensive. In India you get plenty of sweetened/unsweetened Khoa, right?
Everyone was assuming you need it for making a khoa based sweet! Ricotta is dry roasted to make a texture like khoa. In chennai, you can definately find it as Prime Deli - as per this link
Thanks Arch, yep here in US i use ricotta for milk sweets but there we do get khoa for sweets. i tried lasagna with cream cheese and other cheeses and came out well. found few lasagna recipes without ricotta in it.
checked the link u gave and surprised to see modhakam, sevai etc are avalable ready made now.
There is a adambakkam based unit which serves sevai, idli with milagai podi, modhakam, chapathis with alu curry on a regular basis to almost all super markets. It is their advertisement on that link
