Soak the sago|javarisi in yogurt for 3 hours. You need to mix it well with your hands. After soaking it will be doubled in size.
In a wide bowl add the sago mixture, rice flour, chili powder, cumin seeds, butter, hot oil, salt, and asafoetida.
Sprinkle little water as needed and make it into a soft dough.
Put it into a murukku press and press it into the hot oil.
It won’t come as full murukku. I tried this 2 times with 2 different murukku achhus. You can use any achu of your choice.
I used a new achu with 4 holes.
Heat oil and fry and when the oil sound subsides take them out from the oil.
Drain with a kitchen towel. Crispy murukkus are ready.
Store in an airtight container and enjoy the murukkus.
