Thank you all for helping me to figure out what is Pachari..
From all your comments, this is what I understand.
1. Pachari ie the one I am familiar with..tiny grains of rice that is white in colour is only available in Kerala.
2. All grains except parboiled ie Kuthari is classified as pachari.
Now that we have sorted that.. What is Chakkari?
I grew up during IR8 nellu season. There were only four types of rice available then.
1. Mesha Ari = Basmati. ( Some of the old Kerala recipe books in English actually uses the term table rice for Basmati and I have always wanted to know, why basmati is called Mesha/table rice. If you know, please leave a comment.)
2.Kuthari = parboiled rice
3.Pachari = not parboiled rice
4. Chakkari ???????
I am away the next two days. Back on Wednesday.
