I’ve been watching this thread with interest. Here is my $.02:
Dracula theme for ladies screams (no pun intended) Old World posh Transylvania with and a little bit of tongue in cheek: more about decoration than anything else. Brass candle operas with black or deep red candles, cheesy ornate goblets with sugared fruit pouring out, and dry ice is a must.
I love the cotton candy idea. Can you see a vertical dessert display with mounds of wispy white cotton candy as fog/mist creeping around it? Black and deep red petites fours, maybe some simple dark chocolate ganache tartlets with a smidge of edible gold.
I once did a Halloween ladies to-do and did the caviar thing, it worked well. I also stuffed jumbo black olives with a cream cheese roasted garlic mix and then stuck them on toothpicks in a topiary type display. Maybe some marinated cherry tomatoes in cool glass pedestal containers for color.
I just can’t get Vlad the Impaler out of my head. A stake through the artichoke heart? Something with pomegranates as drops of blood.
By the way, I don’t know about your area, but around here you can only purchase dry ice 5 pounds at a time, something to do with it being used in crystal meth production. You might want to check and stock up in increments if you have to.
