Have you ever wondered how to make edible slime? Perhaps you’re throwing a haunted Halloween party and are in need of some scary green ectoplasm. Maybe you’re wearing a Ghostbusters inspired costume and have just been slimed.
What is ectoplasm?
Before we get to the recipe let’s discuss ectoplasm…. Although I have to credit the Ghostbusters franchise for introducing me to ectoplasm, the concept has been familiar among spiritualists for a long time. Ectoplasm, or ghost slime, is a viscous green substance that is given off by a paranormal entity when they interact with the physical world. Every time a ghost touches a human or makes a chandelier move, a green slimy residue is left on the object touched by the ghost.
How To Make Edible Slime
The great thing about this slime recipe is that you can use it both for decorating and for eating. Slather it on your Halloween platters and buffet table. Drip it down your bathroom mirrors. Serve it to your guests for dessert. It looks very real and disgusting but tastes like vanilla custard. And it’s vegan!
I must confess this recipe started out as a failed attempt to make a coconut-free vegan whipped cream. But the texture was way too slimy. ‘Eureka!’ I thought. I added some green food coloring and had made edible green slime.
To make your own ghostly green ectoplasm, mix equal portions of canola oil and vegan milk in a large bowl with an electric mixer. I used soy milk but this should work with any vegan milk. Add in the vanilla extract and the xanthan gum and mix until combined. The xanthan gum is what makes this viscous and slimy and you can buy this at Whole Foods or any store that has gluten-free baking supplies. Next add the icing sugar in three or four stages blending completely in between. In addition to adding sweetness the icing sugar thickens the slime.
Finally you can add your green coloring until your desired color is achieved. I used Wilton cake icing gel in Leaf Green color. What I really like about gel colors is that they don’t water down your mixture. But, you can absolutely use regular liquid food coloring. Just add some additional icing sugar if you find your slime is becoming too liquid.
