In a bowl add salt, turmeric, chili powder, black pepper, ginger garlic paste, green chilies, cilantro, mint, lime juice and toss well. Set aside for 15 minutes or a few hours in the refrigerator.
When ready to cook, add in the chickpeas flour, rice flour, and toss well to combine. If needed add a tiny amount of water, about 1 – 2 teaspoons water. Mix well. Batter should lightly coat the shrimp.
Heat oil for deep frying, it should be 375 F. Drop shrimp into the 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 minute per side. Remove from oil, transfer on paper towel to drain the oil. Cook remaining shrimp.
When ready to serve, add a drizzle of balsamic vinegar on top.
