Ina Garten's recipe, and we've had some fun over the years at The Kitchn with our own riffs including the always-popular Irish Shortbread Toffee Bars and Cardamom Vanilla Shortbread with White Chocolate and Rose Petals. But on days when you're in the mood for keeping it relatively simple yet still adding your own touch, consider one of my favorite mix-ins. As for how much to add, it certainly depends on your recipe and you don't want to incorporate too many chunks into your dough because then it will become quite difficult to roll out or slice. My blanket suggestion, then, is to start with 1/4 cup of your chosen mix-in (with the exception of espresso powder and chopped herbs: begin with 1 tablespoon. For flaky salt, a sprinkle will do) and see how the dough looks. It should be studded with little bits of mix-in here and there but shouldn't be so crowded that you wouldn't be able to work with it.
