Take a long white serving platter like the one in the above photo and add several crumpled-up Band-Aids.
Now, drip red food coloring all over the serving platter, and make small garish puddles. You can even add drops of table syrup to the edges of the puddles or bits of blackened marshmallows to give them that old coagulated blood look.
Line up your shot glasses on the platter and pour 1 ounce of whiskey (depending on how big your shot glasses are).
Pour in 1 ounce of hard cider.
Next, add drops of red food coloring to give the shot that "is this blood I'm chugging?" look. Looks good so far; you'll have the vampires salivating!
Carefully add 3-4 mini marshmallows or a single regular-size marshmallow into each shot glass.
Now comes the fun part. Using the chef's butane torch, caramelize the marshmallows. Be careful not to set the liquor aflame. You may want to stick the marshmallows on the end of a fork and char them instead of risking a fiery booze-fueled marshmallow inferno.
