I start by slicing each string cheese stick into three equal pieces, giving me a good amount of cheese to work with for the broom part. Cutting off slightly more than you think you need is smarter than ending up with a tiny piece you can't shape properly.
Before doing any peeling, I push a pretzel stick about halfway into one end of each cheese piece. Doing this step first matters, since peeling the cheese before adding the pretzel risks tearing it apart before you're ready.
Once the pretzel is in place, I use my fingers or a paring knife to gently peel and separate the open end of the cheese into thin strands. This is what actually turns a plain cheese stick into edible broomsticks that look like a proper witch's broom.
Next, I wrap a fresh chive around the cheese just below where the pretzel meets it, tying it into a simple knot. This one small detail is what makes these look like genuine broomstick halloween treats instead of just cheese on a stick.
Once each broom is tied off, I stand them upright on a small plate or tray so they look like little brooms leaning together. They're ready to eat right away, so there's no waiting around once you're done assembling.
