Soak red lentil at least for 1hours or more.
Pet dry zucchini slices and keep aside.
Blend dal to smooth batter, using just enough water needed to blend.
To make Pakora batter add corn starch, salt, chili powder and salt together, mix it well, whipping for few seconds. Add all the other ingredients to the batter, ginger, green chili, cilantro and mix all the ingredient well. Batter should be consistency of pancake mix, if needed add little water.
Heat the oil in a frying pan on medium-high heat. The frying pan should have about 1 inch of oil. To check if the oil is ready, put one drop of batter in the oil. The batter should come up but not change color right away.
Dip the zucchini slices into the batter one at a time, making sure it is covered by the batter completely. Then, slowly drop into the frying pan.
Fry the pakoras in small batches, not overlapping. The pakoras will take about 4-5 minutes to cook.
Turn them occasionally. Fry the pakoras until both sides are golden brown. If the oil is too hot, the pakoras will brown too fast and not get crispy.
Left over batter, place about one tablespoon of batter into the oil. Fry the pakoras in small batches until golden-brown.
The crispy, delicious pakoras are now ready to serve. I like to serve these both pakoras side by side.
