Do you recognize the shapes of these spritz cookies? Theoretical physicists and nuclear engineers might. They are representative of a hydrogen atom in several different states. Oh, and they’re delicious. [Windell] over at Evil Mad Scientist Labs cut his own spritz cookie discs in order to bake the hydrogen look-a-likes.
To bring you up to speed: spritz cookies are not rolled out and cut with a cookie cutter – although you could print your own cutters in these shapes if you wanted to. Instead, a cookie press is used to squeeze out dough onto a baking sheet. The press looks like a very wide syringe. The dry dough is packed into a cylinder, and a ratcheting ram presses it toward the business end. A disc with wisely placed slits lets the dough squeeze out into the final shape.
We made some shamrocks for St. Patrick’s Day, but now we’re wondering if we can make our own Hackaday logo cookies. [Windell] grabbed some melamine dinner plates to use as raw material for his custom discs (remember to use food safe material). He then designed the cutouts in Inkscape and headed over to the laser cutter to fabricate the disc. We don’t have a laser cutter but we’d bet you can do a similar, but slower, job with a drill and a lot of filing/sanding.
