Wash and pat dry carrots. Line carrots on a parchment-lined baking sheet and coat lightly with oil
Place into the oven and set timer for 45 minutes
As carrots are roasting, start making the glaze by juicing one Sumo Citrus and add the juice, honey, olive oil, curry powder, and cinnamon into a small pot
Combine the arrowroot powder an water in a small bowl. Mix and set aside
Bring the pot to a simmer over medium-high heat. Remove from the heat and pour in the arrowroot mixture. Whisk vigorously until sauce thickens
Once carrots are finished roasting (you may need an additional 5-10 minutes, depending on size of carrots and oven) pour the glaze over the carrots and serve immediately
