Heat 1 tablespoon of the oil in a large saucepan over medium-high heat until shimmering. Add the carrots and 1/2 teaspoon salt and cook until they begin to soften, 5 to 7 minutes. Stir in the garlic, coriander, cumin, ginger, chili powder and cinnamon and cook until fragrant, about 30 seconds. Add the water and bring to a simmer. Cover, reduce the heat to low, and cook, stirring occasionally, until the carrots are tender, 15 to 20 minutes.
