Make a template. Trace your hand onto parchment or wax paper and place it on your serving board. This is optional but makes it much easier to create realistic proportions.

Arrange the fingers. Place the prosciutto-wrapped mozzarella pieces over the finger portion of your template. Trim the pieces as necessary to create different finger lengths.

Create the palm. Position the smaller log of goat cheese directly underneath the fingers to form the palm of the hand.

Add the wrist and forearm. Place the larger goat cheese log beneath the palm. Gently shape the cheese as needed so the sections resemble a hand, wrist, and forearm.

Transfer to your serving board. If you assembled the hand directly over your parchment template, carefully transfer the pieces to the board and remove the parchment.

Cover with prosciutto. Drape the remaining slices of prosciutto over the goat cheese palm, wrist, and forearm. Allow the prosciutto to naturally wrinkle and overlap for a more realistic, creepy appearance.

Make the fingernails. Cut five small fingernail shapes from the tomato and place one at the end of each mozzarella finger.

Finish the board. Arrange crackers and your favorite charcuterie additions around the hand.

Serve. For an extra spooky touch, place a cheese knife into the prosciutto hand before serving. Serve chilled or slightly cool and enjoy.
