Remember back when I used to offer non-caffeinated baking mixes? This Chai Shortbread recipe was the basis for the Chai Shortbread cookie mixes! Absolutely delicious, and super easy to make.
A note about shortbread: The secret to great shortbread is to NOT develop the gluten. This is the reason for the cornstarch in the recipe - a "secret" ingredient for many families of shortbread makers. Cornstarch does not develop gluten.
Additionally, this is why you should be very careful not to over beat the mixture once the dry ingredients have been incorporated! Much like how kneading bread dough is to develop the gluten - giving bread structure - over beating the mixture will do the same to these cookies. In this case, you don't want developed protein, and strong structure - you want tender, flaky, melt-in-your-mouth shortbread - so Mix JUST until combined!
The fact that there isn't a lot of developed gluten is also why these cookies are incredibly delicate when warm, so be GENTLE handling them!
