In a bowl, take the flour, sambar powder and salt. Slowly add water and knead to a soft dough.
Heat a kadai with cooking oil.
Divide the dough into equal balls, dust and roll out into thin discs. Using a knife cut into diamond cuts. Pick on top with fork, else these will puff and will become soft.
Drop into the hot cooking oil and fry in simmer till you get a cripsy chips.
Drain from fire and store in an air tight box.
Notes
Since the dough tends to become soft, you got to fry these on low flame.
