To make Nimki, start by combining maida, salt, baking powder, red chili powder, nigella seeds, ghee, and oil in a food processor. Mix well. Gradually add water, about a cup, until you form a firm dough.
Remove the dough, cover it with a damp cloth, and let it rest for at least 30 minutes. Divide the dough into 5-6 equal-sized balls.
Roll out each ball into a thin circle. Cut the circle into half-inch strips, and then cut again from the other side to create diamond shapes.
Heat oil and ghee in a deep pan for frying. Fry the Nimki in batches (I like to fry those prepared from one circle at a time, but adjust based on your pan size and oil quantity). Fry over low heat until they turn a beautiful golden brown.
Remove the fried Nimki with a slotted spoon and place them on tissue paper to drain any excess oil.
Once cooled, store your Nimki in an airtight container. Enjoy this delightful snack with a cup of hot tea or coffee!
