In a large Dutch oven, melt the butter over medium-high heat. Add the turmeric and cumin, stir, and cook one minute until fragrant.
Add the rice, salt, and ground black pepper to the pot and stir to coat. Cook rice four minutes, stirring frequently, until lightly toasted.
Stir in the chicken broth. Bring mixture to a boil, cover the pot, reduce heat to a simmer, and let rice cook 15 minutes without disturbing it. (Seriously. Do not lift the cover!)
Remove the covered pot from the heat and turn off the stove. Let rice rest in the pot, covered, for about 15 minutes, until the water is completely absorbed and the rice is tender. Fluff rice with a fork before serving.
