These holiday shortbread thimble cookies made with nuts and jam or jelly are a delicious Christmas treat that everyone loves.
Sifting the flour before you measure it is very important to making shortbread that is fluffy and light.
Similarly, make sure you beat the butter and sugar well before adding other ingredients. The butter should be fluffy and the sugar should be dissolved into it. This is much easier to do if the buffer is room temperature when you start. If you forget to take it out of the refrigerator, microwave it for a few seconds to soften it.
Mixing the flour in by hand is another important step to prevent the cookies from being too tough.
Use a jam or jelly that isn't too runny, otherwise you will have trouble keeping it on the cookie.
