Peel and devein shrimp. When using frozen peeled shrimp, place the shrimp in lukewarm water for about ½ hour to completely thaw the shrimp.
Wash and squeeze out as much water as you can from the shrimp. Or place in a colander or a strainer to drain the water.
Sprinkle, salt, turmeric, chili powder, black pepper powder, ginger garlic paste, green chilies, cilantro, mint, lime juice and toss well. Keep aside for 15 minutes or for a few hours in the refrigerator.
When ready to deep fry, sprinkle chickpeas flour, rice flour and toss well to combine. If required add some water, about 1 - 2 tablespoons. If there is some moisture in the shrimp, you may not need any water. Batter should lightly coat the shrimp.
Heat oil for deep frying, it should be around 375 F. I do not measure the temperature.
Drop shrimp into hot oil. Don’t overcrowd the pan. If the pan is crowded or if oil is not hot enough, the batter coating could fall off the shrimp. Depending on the size of the pan, fry the shrimp in 2 - 3 batches.
Deep fry shrimp on medium high flame until golden and crisp, about 2 - 3 minutes per side.
Remove from oil, drain a paper towel. Fry remaining shrimp.
Serve with green chutney or as is.
