Shrimp Pakora Sliders With Coconut-Cilantro Chutney

Process cilantro, mint, cumin, ginger, garlic, and serrano chile in a food processor until chopped, about 20 seconds, stopping to scrape down sides of bowl as needed. Add flaked coconut, coconut milk, and salt; pulse until combined, about 3 pulses. Chutney may be stored, covered, in refrigerator up to 5 days.

Toss together shrimp, onion, lemon juice, and curry leaves in a large bowl. Sprinkle shrimp mixture with chile powder, cumin, and salt; toss to coat. Set shrimp mixture aside while you prepare the batter, but do not let stand longer than 10 minutes before cooking.

Whisk together besan, cornstarch, and turmeric in a medium bowl. Working in batches, transfer shrimp mixture to besan mixture in bowl, and toss until fully coated. Transfer coated pieces to a baking sheet. Repeat process with remaining shrimp mixture. 

Pour oil into a large Dutch oven to a depth of 2 inches; heat over medium until a deep-fry thermometer registers 350°F. Working in about 5 batches, fry about 7 pieces shrimp and onion in oil until golden brown, 2 to 3 minutes per batch, flipping pieces halfway through cook time. Using a slotted spoon, transfer fried shrimp clusters to a paper towel-lined plate; immediately sprinkle with chaat masala and salt to taste.

Smear a little Coconut-Cilantro Chutney on the inside of each bun. Top evenly with fried shrimp and onion.
