Haloween Fingers

Ok, Halloween has passed, but here it is a funny idea for your next year's Halloween aperitif.
I tried it for the first time a week ago at a great Halloween party of some dear friends of ours (thank you btw!!!) and everyone was excited with it!
So easy, so scary, so tasty... can you do better? ;)
With terror from me to you... BoooOOOOO
