Take ¼ cup of soaked rice and 1.5 cup of soaked green gram dal (moong dal) in a mixture grinder.
Blend them nicely. Transfer to a bowl when done. Check the texture. (Pro tip: Blend it a little bit more if the paste is not smooth).
Add 1 small piece of finely chopped onion, 1 piece of finely chopped fresh green chili, salt to taste, ½ tsp of chaat masala powder, ½ tsp of black pepper powder, ½ tsp of garam masala powder, and 2 tsp of finely chopped fresh coriander leaves.
Follow it with 4 tsp of bread crumbs. (Pro tip: You can use store-bought bread crumbs. However, I would recommend making them at home by grinding a pack of toast biscuits in your mixture grinder).
Mix them all very nicely.
Rub a little cooking oil on your hand and shape the tikkis.
Coat with bread crumbs. Keep them on a plate aside.
Heat an adequate amount of cooling oil in a kadai on a high flame. When it is hot, reduce the flame to medium and release each dal tikki carefully in the hot oil from one side so that you do not splash hot oil on you. Flip and fry the tikkis till golden brown. Remove them. (Pro tip: You may keep these fried dal tikkis on a plate covered with a piece of tissue paper before serving them finally. This will absorb the excess oil in them. However, do not keep them for long as the steam might overcook them and hamper the desired crunchiness in them).
Your delicious homemade dal tikkis are now ready to serve. Arrange them on a plate, garnish with a few fresh mint leaves, and serve hot.
