Though I am a North Indian, I am born and brought up in Mumbai, a very cosmopolitan city, still has a staple of typical Gujrati and Maharashtrian snacks that we savor during tea-time - chivda (sauted flattened rice with peanuts) , bhel (puffed rice), idlis, dhoklas. These are very different from what North Indians like to snack on - it's usually fried fare like samosas, fried savories like pakodas, namak paare, mathri's etc
This is something my son was introduced to after we came to Delhi and though he hasn't take a big fancy to it, we make it occasionally for a lunch box treat. It's mighty yummy and full of oil and deep fried so you may want to stay away from it if you're on a diet of some sort and cook it only for the kids. It's like a very crispy savory cookie.
I am giving you a rough recipe for this 'coz everything that likes to be fried, I like to keep away from. I give my cook (yeah, I have someone to help me with my kitchen chores) some basic instructions and he whips them up from me. My MIL makes some yummy ones too - she makes them round. These are more bite sized so they can be packed as a snack.
1 cup all purpose flour
1 cup semolina flour / rava
2-3 tablespoons oil
1/4 tsp carrom seeds
1/2 tsp salt
3/4 cup water
Mix all the dry ingredients. Make a well in it and pour the oil or ghee (please do not try this with butter) and mix it all together with your hands. Now, add water to this mixture a couple of tablespoons at a time to bring the dough together into a stiff dough. Use a rolling pin and take 1/2 of the dough and roll it out as thin as you can - about 1/4 inch into a round. Then cut it length and breadth wise into strips to make these tiny sized pieces and pour into hot oil and fry for a couple of mins each side till nice and browned. Remove onto a tissue paper and when absolutely cooled store in an air tight box.
These are very rough instructions and not detailed at all but email me and I can answer all your queries on this.
