In a large mixing bowl, cream butter and sugar until smooth with a hand mixer (or a stand mixer with a whip attachment).
Beat in egg yolk until well combined.
In a separate bowl, whisk well all-purpose flour and earl grey tea. Gradually add the dry ingredients to the wet ingredients and mix until well combined with a silicon spatula.
Transfer the dough onto a sheet of parchment paper (or waxed paper) and shape it into a log. Roll tightly in the parchment paper and refrigerate for at least 2 hours, or overnight.
Preheat the oven to 320°F (160°C).
Remove the dough from the refrigerator. Spread granulated sugar on a piece of parchment paper and roll the dough over the sugar to coat evenly. Slice the dough into thin rounds, about 1/4 inch thick.
Place the rounds on a baking sheet lined with parchment paper and bake for 13 to 15 minutes until the edges are slightly browned.
