Step 2
Heat 1 teaspoon canola oil in a skillet over medium heat. Stir in red chiles and green chiles, 1/2-inch cinnamon stick, pearl onions, coconut, coriander, cashews, cardamom pods, cloves, 1/2 teaspoon fennel seeds, and cumin seeds. Cook, stirring constantly, until spices are fragrant and coconut starts toasting, about 3 minutes. Remove from heat. Transfer to a spice grinder. Add cilantro, mint, and 1 teaspoon water; grind until a smooth paste forms, adding more water as needed.
