Using a paring knife, cut area at the top to resemble fingernail. Cut curved lines to resemble knuckles.
2. Place in boiling water until cooked and plumped.
3. Remove from water and place on plate. Add cashews or sliced onions for fingernails, if desired (I did not do this).
4. Strategically place ketchup around and on fingers to resemble blood.
Enjoy your bloody fingers as is, or in a hot dog bun!
