Semiyan payasam|seviyan kheer|how to make seviyan/vermicelli payasam

Seviyan kheer is the most preferred dessert in my mom's place during any festival or on arrival of any guest. And my mom makes the world's best seviyan kheer. I don't know what she does... but even after trying so many times and following her recipe exactly, still my seviyan kheer never used to taste as good as her's.
