Take besan, black pepper powder, turmeric powder and salt in a bowl. Mix well.
Add hot oil. Mix it well, it will have a crumbly texture.
Then make the dough by adding little water at a time and make a soft, smooth dough. It is very sticky dough so you may need to grease your hand halfway through.
Making sev recipe:
Now use your sev maker machine with a disk which has tiny small holes. Grease the inside of sev maker with little oil.
On the other side, heat the oil in a pan on medium heat for deep frying.
Now fill the container with prepared dough and close it tightly.
As you twist the handle sev will come out from the bottom holes.
Once the oil is hot, hold the machine over the pan, turn the handle and thin sev starting to fall into the hot oil. As it falls into the oil, slowly move the machine in a circular motion.
As you complete one circle, stop there and reverse the handle a bit to stop coming out.
Fry both the sides till it becomes crispy. You will see it will stop bubbling, meaning it is ready. Remove it using a slotted spoon.
And place it on the paper towel-lined plate. And continue the same process for remaining dough.
Let it cool completely, as it cools it will become crispier. Then break it and crush it lightly with your hand.
Once cools completely you can store in an airtight container.
Notes
For a variation, you can add spice powders like red chili powder, crushed dried mint, amchur or any other ready masala.
