if the cholar dal becomes thick after its pressure cooked, then add some water to thin it. the consistency of the dal can always be adjusted by adding less or more water after its cooked. you can also slightly keep the consistency thin then what it is usually if you prefer.
avoid asafoetida or hing to make a gluten free version of this dal.
to get hints of gingery taste in the dal, you can add ½ inch ginger - either grated or crushed into a paste in a mortar-pestle. just fry the ginger after you have finished frying the whole spices and asafoetida.
