In a mixer jar / blender , add 1 cup grated beetroot (tightly pressed) , 1 green chilli and ½ inch ginger , blend everything together to get beetroot puree. Adding green chilli and ginger is truly optional .
In a mixing bowl , add 2 cups whole wheat flour , ¼ teaspoon carom seeds and salt.
Add beetroot puree and mix well.
Now add in ½ - ⅔ cup water in batches and bring flour together to form a smooth dough . Add water part by part as it depends on the quality of wheat flour. I added around ½ cup plus a tablespoon to get a smooth dough.
Add 1 tablespoon of oil , spread on dough and cover dough with a damp cloth and set it aside for 20 minutes.
After 20 minutes , knead dough once. Pinch some dough, make lemon size balls and set aside. I got around 11 balls of medium size. Close it damp cloth and keep aside.
Dust some flour on worktop surface , take lemon size dough ball , flatten it and roll into a round circle of around 6-7 " inch diameter. Grease some oil on top of rolled dough.
Tightly roll dough like a log . Starting from one end , wind dough circularly to form a spiral shape .
Lightly press the spiral dough and roll it into a circle of 6-7 ' diameter.
Alternatively , you can just roll it into a circular disk of 5-6 " inch and make phulka without adding any oil . Or else as a traditional chapathi , you can even apply oil , fold and roll roti . However you roll , beetroot roti comes out well.
Heat griddle /tawa . Keep the flame on high heat , place rolled roti on hot griddle , drizzle some oil / ghee at corners and on top . Flip and cook on other side.
Apply ghee/ oil on other side too. Gently press roti ,flip and cook on other side too . Keep flipping roti , alternatively on both sides for every 3-4 seconds. It doesn't take more than 40-45 seconds to make a single roti. Once you see brown spots , its done. Remove it and place on a roti basket lined with cotton napkin.
Serve Roti accompanied with dal and any sabji of your choice.
