Preheat oven 180'C/Gas mark 4.
Rub butter, caster sugar and flour together in a big bowl until it looks like breadcrumbs, I used to call this tickling with the boys. Now we just add it all to the food processor or mixer and pulse it at 5 second intavals.
Heat a small cup of milk and add the chai and allow to steep. Strain after 4 minutes.

Add a tablespoon of milk to your bread crumbs and knead for a minute or two until it forms a smooth ball of dough. Cover with plastic film and pop in the fridge for half an hour.
Turn onto a floured surface and roll out the dough until it's 1cm or 1/4 inch thick.
Cut out biscuit shapes using your template and put a hole with a straw in for the string.

Reshape the scraps and cut more shapes.
Place the biscuits on a baking tray lined with parcement paper or a silicone liner and prick with a fork.

Bake for 15 minutes before placing on to a wire rack to cool.
Store in a sealed container and keep in a cool, dry place. Shortbread will keep well for weeks but is also excellent after being frozen. If you plan to keep your shortbread for more than two weeks, I’d suggest freezing it.
Adaptations - You can use Earl Grey instead of Chai to flavour your milk - if so I would add a dash of vanilla extract to compliment the flavour.
