Wash and dry all produce. Halve, peel, and finely dice onion. Dice tomato. Zest and quarter lime (quarter both limes for 4 servings). Mince cilantro leaves and stems.

Melt 1 TBSP butter (2 TBSP for 4 servings) in a medium pot over mediumhigh heat. Add half the onion and cook until slightly softened, 1-2 minutes. Stir in 11/4 cups water (21/4 cups for 4), stock concentrate, 1/4 tsp turmeric (1/2 tsp for 4; we sent more), and salt. Bring to a boil, then stir in rice. Cover and reduce to a low simmer. Cook until rice is tender, 15-18 minutes. Keep covered off heat until ready to serve.

Pat chicken dry with paper towels; season all over with salt, pepper, and a pinch of chipotle powder (use up to 1/4 tsp if you like spicy food). Heat a large drizzle of oil in a large pan over medium-high heat. Add chicken; cook until browned and cooked through, 3-5 minutes per side. (TIP: Lower heat if chipotle powder is browning too quickly.) Turn off heat; transfer to a cutting board.

While chicken cooks, combine tomato, cilantro, and 2 TBSP onion (3 TBSP for 4 servings) in a medium bowl (taste and add more onion if desired). Squeeze in lime juice to taste. Season with salt and pepper. Set aside, stirring occasionally, until ready to serve.

In a small bowl, combine sour cream, lime juice and zest to taste, and a pinch of chipotle powder (for an even spicier kick, use up to 1/4 tsp). Season with salt and pepper.

Fluff rice with a fork; stir in 1 TBSP butter, half the salsa, any remaining lime zest, salt, and pepper. Divide between bowls. Slice chicken crosswise; arrange over rice. Top chicken with spicy lime cream and remaining salsa. Cut any remaining lime into wedges; serve on the side.
