Wash, peel the potatoes and cut them into little thick slices (about 1/4" thick).
After all, potatoes are sliced, add salt, lemon juice, garam masala, red chili powder, and finely chopped coriander. Mix well.
Keep aside for 5-7 minutes for marination.
Add some oil in a pan and spread on the whole surface.
Turn the heat down to low-medium.
Spread semolina in a plate. Dredge potato slices with semolina. Ensure that both sides of the potato slices are well-coated.
Gently place the potato slices on a nonstick pan and let them fry till the face touching the pan starts to brown.
Flip the potato slices over. Drizzle a few drops of oil in the pan, if required.
Fry them until brown and crisp.
Repeat till all the potato slices are fried.
Serve hot with sauce or dip.
