Lightly whisk together the flour, tea and salt in a small bowl and keep aside. In a large bowl, beat together the soft butter, sugar and the orange zest with an electric mixer until light and fluffy. Add the egg and beat it in.

Add the flour mixture and mix well with a wooden spoon or your fingers but do not over mix or knead the dough. Pat the dough into a disc, wrap in cling film and refrigerate for about half an hour.

When the dough is firm enough to handle comfortable, roll it out on a lightly floured surface until it is 1/4" thick. Using a 2 1/4" cookie cutter cut out cookies and place them an inch apart on a lined baking sheet. Collect the craps and clump them together and roll out and cut more cookies from it. Do not knead but make sure the dough is a smooth ball otherwise you will have cracked cookies!

Refrigerate them for about 15 minutes and then bake at 180C (350F) for about 15 minutes or until the edges and bottoms of the cookies are golden. Do not over bake them. Let the cookies cool on a wire rack before serving. Store them in a airtight jar.
