Goan Tangy Spiced Chicken Drumstick Curry

Score each chicken drumstick twice across the thickest part of the meat down to the bone using a chef's knife on a clean cutting board, then transfer all drumsticks to a glass mixing bowl, taking care to sanitize hands and tools immediately to prevent cross-contamination.

Heat a dry skillet over medium-low heat at 150°C (300°F) and toast the dried chiles, cumin seed, broken cinnamon stick, coriander seed, black peppercorns, and whole cloves for 2 minutes, shaking the skillet continuously until the seeds become fragrant and deepen slightly in color.

Transfer the toasted whole spices immediately out of the hot dry skillet onto a plate and allow them to cool at room temperature for 3 minutes.

Add the cooled toasted spices, sliced fresh ginger, garlic cloves, ground turmeric, and cider vinegar into a spice grinder, then puree on high speed for 90 seconds until a smooth, thick, vibrant crimson paste forms.

Rub half of the blended vinegar spice paste and 4 grams of the salt evenly into the scored chicken drumsticks in the glass mixing bowl, then let marinate at room temperature for 20 minutes.

Place a heavy-bottomed Dutch oven over medium heat at 175°C (350°F) and heat the vegetable oil for 2 minutes until the oil shimmers across the bottom.

Add the finely diced red onions to the Dutch oven and sauté over medium heat for 8 minutes, stirring frequently with a wooden spoon until soft, sweet, and deeply golden brown.

Add the remaining half of the vinegar spice paste into the caramelized onions and fry over medium heat for 3 minutes, stirring constantly until the raw vinegar aroma mellows and small oil droplets begin separating from the paste.

Add the marinated chicken drumsticks to the Dutch oven in a single layer and sear for 5 minutes, turning every minute with the wooden spoon to coat the meat thoroughly with the hot spiced onion paste.

Pour the 250 ml of water into the Dutch oven, scrape up any caramelized residue from the bottom of the pot with the wooden spoon, and stir in the brown sugar and the remaining 4 grams of salt until combined.

Bring the liquid to a rolling bubble, reduce the heat to low at 95°C (203°F), cover the Dutch oven tightly with its lid, and simmer gently for 25 minutes.

Remove the lid and simmer uncovered over medium-low heat for 5 minutes to reduce the sauce slightly until it coats the back of a spoon, then verify using an instant-read meat thermometer inserted into the thickest part of the drumsticks without touching bone that the internal temperature reaches at least 74°C (165°F).

Remove the Dutch oven from the heat and allow the curry to rest uncovered for 5 minutes before portioning onto serving plates alongside warm basmati rice or crusty bread.
