1 tbsp. finely ground Earl Grey tea leaves, from about 3 tea bags
½ cup light brown sugar
¾ tsp. kosher salt
½ tsp. orange zest, finely grated
1 large egg
2 tsp. vanilla extract
2-½ cups all-purpose flour
½ tsp. baking powder
½ tsp. baking soda
Instructions
Pre-heat oven to 350°F and line two half-sheet pans with parchment paper.
Put 1/2 cup granulated sugar in a small bowl, or shallow dish; set aside.
Combine the butter and tea leaves, in a small saucepan, set over medium heat; melt the butter, stirring occasionally, until it just begins to sizzle around the edges; remove from the heat and let cool for 5 minutes.
Add the tea butter, to a large bowl, and add brown sugar, salt, orange zest and remaining ¾ cup granulated sugar.
Use an electric mixer, on medium speed, or a whisk, to combine for about 30 seconds; the mixture will be grainy and separated.
Add the egg and vanilla; mix until combined and smooth; about 30 seconds.
Add the flour, baking powder and baking soda to the bowl; mix, on low speed, or with a rubber spatula, until just combined; use the spatula to scrape the sides and bottom of the bowl to ensure the dough is evenly mixed.
Use a 2 tablespoon cookie scoop to portion the cookies; alternatively, measure 2 tablespoons of dough with a measuring spoon.
Roll each dough ball in the reserved granulated sugar, then place on the baking sheets 2-inches apart.
Place in the pre-heated oven and bake the cookies until set; light golden around and crackled on top; 16 to 19 minutes; rotating the sheets from top to bottom and front to back in the oven halfway through the baking time.
Remove cookies from the oven and let cool on the baking sheets.
Store cookies in an airtight container, at room temperature, for up to 3 days, or for a few weeks, in the freezer.
Notes
Try substituting English Breakfast tea and lemon zest instead of Earl Grey tea and orange zest.
