1. Heat peanut oil and butter in a large straight-sided skillet over medium-high heat. Add onions, chile, ginger, and chopped cilantro stems. Cook, stirring occasionally, until onions soften and golden, about 10 minutes.

2. Add curry paste and chicken; stir to coat. Season with salt and pepper. Add tomatoes and coconut milk. Fill one empty can with water and add to skillet; stir to combine. Bring to a boil, then reduce heat to a simmer. Cover and cook, checking curry occasionally to make sure it does not begin to dry out and adding water, if necessary, until chicken is tender and cooked through, about 20 minutes.

3. Top curry with yogurt and sprinkle with almonds and cilantro leaves. Serve with rice and lemon wedges.
