Adai

One cup urad
One cup thoor
One cup chana
One cup rice
coconut
red chilli

umm, I make any dal 3 :1(rice).  it works. good wholesome food
soak all but coconut.  a couple of hours. grind.  add coconut( optional but it gives a nice fluffy, crispy feel to the adai).  Make adai on Tava.  first ones can be troublesome. 
To prepare the tava for an onslaught of dosais or cousins of.... heat tava, spead some oil,heat for a bit and splash water.  the tava gets coated with nonstick something. try to get an iron tava.  everything tastes better on it.
