Step 1

Heat oil in a large pot over medium-high. Cook cayenne, cumin, and turmeric, stirring, until fragrant, about 1 minute. Add onion, garlic, and ginger and cook, stirring, until softened, about 3 minutes. Add apple and lentils and stir to coat. Stir in coconut milk and 2 1/2 cups water and bring to a boil. Reduce heat and simmer, stirring occasionally, until lentils are completely soft and dal is thick, 20–25 minutes. Add lime juice and season with salt and pepper.

Step 2

Divide dal among bowls and top with yogurt, cilantro, and coconut flakes; season with more pepper.
