Take a bowl, and add gram flour, rice flour, red chili powder ,turmeric powder, hing, chat masala and salt as per taste. Mix them well and keep aside.
In another bowl take peanuts. Now add lemon juice and mix it well.
Add the prepared gram flour-rice flour mixture and toss the peanuts using a spoon until they are evenly coated.
Add a teaspoon of oil and mix again.
Sprinkle little water at a time and mix well until each peanut is coated well with masala.
Take a microwave-safe bowl and lightly grease the bottom with oil. Transfer a portion of the coated peanuts into the bowl, spreading them out in a single layer to ensure even cooking. Avoid stacking them on top of each other.
Add 1-2 teaspoon oil on top of peanuts and place the bowl in microwave on high for 1 Minute.
Stir the peanuts after 1 minute to ensure even cooking, then place them back in the microwave for another 2 minutes.
Allow these peanuts to cool down after 2 minutes. As they cool down they become more crunchier.
Masala peanuts are ready and serve with hot chai.
