This is the recipe I use for edible fake blood.
You can use it on your fake zombie bites or vampire fangs or just decorate your wall to make it look like a murder scene..!
You could also splash it over some sweets or buns and stuff so that your trick or treaters get a fright..
And its pretty nice tasting to so you could just use it as a drink or in your halloween cooking..:)
