2 navel oranges (262 grams), cut into 1⁄8-inch-thick slices
3 cups (720 grams) cold water, divided
1¾ cups (350 grams) granulated sugar, divided
Instructions
Preheat oven to 250°F (130°C). Line a rimmed baking sheet with parchment paper; top with a wire rack.
In a large cast-iron skillet, bring orange slices and 2 cups (480 grams) cold water to a simmer over medium heat. Cook, without stirring, for 6 minutes; drain.
Return orange slices to skillet. Sprinkle with 1 cup (200 grams) sugar. Pour remaining 1 cup (240 grams) cold water over sugar, stirring to combine. Bring to a simmer over medium-low heat; cook for 15 minutes. Carefully remove orange slices from sugar water; arrange in a single layer on prepared rack.
Bake for 30 minutes. Place remaining ¾ cup (150 grams) sugar in a shallow dish. Dredge orange slices in sugar, turning to coat both sides. Return to rack; let dry for at least 2 hours.
