Hi spooks! I like your ideas, except the kitty litter cake, just can't warm up to that : )
I remember the night I turned 21, many moons ago, I drank gin & tonics in a nightclub...they GLOWED IN THE BLACKLIGHTS! I found a recipe somewhere online using this effect with a drink of gin & midori liqour. They used Mt. Dew tho, and i find that unappealing...thinking of trying some pre-party mixes (strictly quality control, of course) with pellegrino, 7-up, or maybe even margerita mix. They called these Toxic Waste, btw.
I'm shooting for more elegant foods this year, with over-the-top decorations, maybe also a little nod to Halloweens of my youth with some kind of cool retro-type decorations.
Making my own corn chips in the shape of bones to go with an incredible Butternut-chipotle dip I tweaked from an allrecipes.com quesadilla recipe-
The tradtional pot of vegetarian chile, which most carnivores find scary until the try it.
Maybe Martha Stewarts fried egg rolls...apart from that it's still up in the air. seems all the ideas are in the drinks this year: hot apple cider with Cap'n Morgan's, Sangria, which I believe means bloody anyway, right? (Please, pardon my crummy spanish if I'm wrong) Certainly going to try the vampire martinis!
