Kerala-Style Fried Chicken with Coconut Oil and Curry Leaves

Purée chiles, garlic, buttermilk, cilantro, mint, ginger, and salt in a blender until smooth. Place chicken in a large bowl, add buttermilk mixture, and toss to combine. Cover and chill at least 4 hours and preferably 24 hours.

Fit a large cast-iron skillet or other heavy straight-sided skillet (not nonstick) with deep-fry thermometer; pour in vegetable oil to measure 1" and heat over medium-high heat until thermometer registers 325°.

Place flour in a shallow bowl. Remove chicken from marinade, scraping off excess, and pat dry. Dredge chicken in flour, shaking off excess. Working in 2 batches, fry chicken, turning often with tongs and adjusting heat to maintain temperature between 325°–350°, until skin is deep golden brown and an instant-read thermometer inserted into thickest part of chicken registers 165°, 10–12 minutes for wings and 12–15 minutes for thighs, legs, and breasts. Transfer chicken to a wire rack set inside a baking sheet and brush with coconut oil.

Fry curry leaves in vegetable oil until sizzling, about 1 minute; transfer to a paper towel–lined plate.

Serve chicken with fried curry leaves and peach chutney.
