Just to clarify, this isn't a curry recipe, it's a recipe for curried rice. Much simpler than putting together a complex — and quite delicious, might I add — curry sauce, this rice recipe comes together in 20 minutes and is a great side for grilled chicken, fish, or steak.
In a medium-sized saucepan, heat the olive oil and butter over medium heat add the onion and curry powder. Sauté until the onion is translucent and curry fragrant, about 5 minutes. Add the chicken stock, season with salt, to taste, and bring to a boil. When boiling, add the rice, stir, and reduce the heat to a simmer. Simmer, covered, for 20 minutes, or until the rice is fully cooked. Season with salt and pepper, to taste, and serve alongside grilled chicken and sautéed vegetables and chicken.
