1 vanilla pod/bean, split lengthwise, seeds scraped and reserved
3 cups (600 grams) granulated sugar
Instructions
In a medium saucepan, bring 3 cups (720 grams) water and tea bags to a boil over high heat; remove from heat. Cover and let steep for 20 minutes; discard tea bags.
Peel oranges, and cut peel into ¼-inch-thick slices. Cut oranges into quarters. Add oranges and peel, lemon zest and juice, and vanilla bean and reserved seeds to tea mixture; bring to a boil over medium heat. Reduce heat to low, and simmer for 10 minutes. Discard vanilla bean.
Stir in sugar, and bring to a boil over medium-high heat; cook, stirring occasionally, until mixture is thickened and a candy thermometer registers 222°F (106°C), 15 to 20 minutes. Let cool completely. Cover and refrigerate until set, about 4 hours.
