1. Preheat the oven to 300°F. Place four 6-ounce shallow ramekins on a rimmed baking sheet.
2. In a medium pot, bring the heavy cream and the tea to a simmer over medium heat. Once the cream comes to a simmer, remove the mixture from the heat and let it steep for 15 minutes.
3. Strain the cream (or remove the tea bags), then return it to a simmer over medium heat.
4. While the cream comes to a simmer, whisk the egg yolks with the sugar and vanilla extract in a medium bowl.
5. Once the cream comes to a simmer, pour it gradually into the egg mixture, whisking constantly to combine.
6. Ladle the mixture into the ramekins, filling them almost to the top. Transfer the baking sheet to the oven, then pour hot water into the baking sheet so it comes about halfway up the ramekins.
7. Bake until the custard appears set at the surface but jiggles slightly when shaken, 30 to 35 minutes. Cool the custard to room temperature (about 45 minutes), then refrigerate until completely chilled (at least 1 hour).
8. When ready to serve, sprinkle 1 tablespoon sugar on top of each custard, then shake the ramekin slightly to make sure the sugar is evenly distributed across the surface. Use a torch to brown the sugar into a caramel coating. Serve immediately.
