Use Your Thumbs
Jam-thumbprint cookies never go out of style, and they're ridiculously easy to make. Spoon off teaspoon-sized chunks of dough, roll each into a ball with your hands and set them on the baking sheet. Press each one with your palm to flatten it lightly, then make an indentation with your thumb. Fill with any kind of jam (hint: a small amount goes a long way), or a variety of jams for a rainbow-like array of cookies.
