Using your mixer with paddle, blend the Earl Grey tea leaves with the butter. Allow to sit for 1-2 hours to ensure full flavor of the tea. NOTE - You do not need to grind the Earl Grey Rooibos tea...it will blend well with the butter. If you are using a large leaf tea, run through grinder.
Once the butter has been infused with the tea, preheat the oven to 350° and prepare your baking sheet with either a silicon pad or parchment paper.
Cream the butter and tea mixture with the powdered sugar.
Add the flour and salt and blend until a soft dough is formed. This will take some time and will initially start out very crumbly. Continue to mix and it will turn into a soft dough.
Turn the dough out onto a lightly floured surface and roll out ¼ inch thick.
Cut out cookies in desired shape. If cut in 1½ squares, will yield 36 cookies.
Bake on prepared cookie sheet for 15 minutes or until lightly brown.
Allow to cool on rack.
Once cooled, prepare the glaze. Combine the powdered sugar and lemon juice until thin stream.
Glaze top of cookies. Allow to rest until glaze sets.
