The original recipe (called Shortbread Stars) came from my McCall's recipe box collection, which I subscribed to in the 80's. It was the first shortbread recipe I ever made, and I've never found a better one. The ingredients are so basic and easy that you'll soon have them memorized. Other recipes don't seem to produce the same perfect texture and flavor. My modification to the original was to try using a 9 x 13 pan rather than chilling, rolling out, and cutting into shapes. (Who has time for that, except on special occasions?) However, using a 9 x 13 pan changes the baking time, and the time given is approximate and based on my experience with a convection oven. I tend to overbake them a bit because I like shortbread very crisp. These are perfect with a cup of tea, of course, and ideal for tea parties or even a quick dessert for company. You nearly always have the ingredients on hand. Now you'll never need to buy (delicious but expensive) Walker's shortbread again!
