This is very simple to make & goes with any chutney or sambar.
Bajra flour is readily available & can be used.
Bajra flour - 2 cups
Urad dhal - ½ cup
Salt
Soak urad dhal in water & keep in the fridge for 1 hr.
In the meanwhile, add salt & water to the flour & malke a dough softer than for chappathis.
Take out the urad & grind as fine as possible.
Finally add the flour & give one run.
Ferment for not more than 8 hrs – it will become very sour fast.
On the dosa tava smear a little oil & make thin dosas.
Oil need not be dizzled around & a little smeared on the tava after 2,3 dosas is sufficient.
