Hello R and Sowmiya,
Thanks for your reply. I used 5 ltr. cooker. The vessel's capacity i used inside the cooker is 5 to 6 cups. I used 4 cups of milk. After 2 whistle(I kept in high) i reduced to low-med setting. And it happend at 22nd min.
Should i reduce the amount of milk?(Hope so) Then should i keep the stove in low instead of low to med?
