For this you will need to purchase a hand mold.
This can be found in most Halloween stores that pop up
during the season.
Ingredients:
2 small boxes of Peach flavored gelatin (3 oz. ea.)
Green food coloring
6 ozs. of lite evaporated milk (No other milk will work)
Instructions:
Spray Mold with cooking spray and set aside.
Mix the gelatin in a large bowl with 2 cups of boiling water.
Stir until the gelatin is dissolved.
Next, add enough cold water to the milk to make 2 cups and add it to the bowl. Stir until blended.
Add a few drops of Green food coloring until you get your desired color
and look.
Now, pour mixture into the mold and refrigerate over night.
By wrapping the mold with a towel and placing in a baking pan the mold
will stay level while the gelatin sets.
To remove hand from mold shake mold gently and place a serving plate
over the hand and turn over.
To make hand more realistic use a knife to trim away any excess
gelatin. Put some red food coloring on the cut off end to resemble
Blood.
Garnish and place on the table as a unique table decoration.
Although the gelatin it edible I find that the presence of the hand
on the table creates the effect I need especially when guests try to
gather up the nerve to touch the hand. Screams are sure to follow.
