Y'all are a font of creativity! I love all the ideas, but the vomiting pumpkin is maybe a tad too realistic. Kids would love this one though.
I may even make the black olive spider deviled eggs. They are cute and not too creepy. Spiders creep me out, big time! I had to kill a big one on the backsplash behind the stove tonight. I guess he didn't like it when I turned on the oven to reheat some samoon bread in foil. There's a spider costume for small dogs being circulated on the web that is just too creepy. The eight legs shake, and it's hard to focus on the adorable faces of the pups wearing this costume.
I found this idea that could be presented as a salad course if you're good with a knife and a little artistic. I initially did not like the idea of serving watermelon with the white rind attached, but it is critical to the remarkable presentation, and if you think about it, no worse than serving cantaloupe or honeydew in the rind in wedges. I've seen the latter done even in fancy restaurants as a breakfast garnish. I can still find personal-sized watermelons here, and they would work for this.
There's also this skull centerpieced antipasto platter. You might replace the black bread with fruits. I have no idea why this one creeps me out less than the vomiting pumpkin.
The baked human hand on a bed of mashed potato (No. 3) also seems to be gluten free. I'd probably double the recipe to at least two pound of meat, so your fingers are larger and won't overcook and dry out as much. What could be scarier than a giant baked hand? I would steam or bake the onion used as the wrist bone before inserting it in the meatloaf. I would also shield the "fingers" of the hand with some doubled or HD foil to promote even cooking. No. 1 is also gluten free, but I wasn't particularly drawn, and it just calls out for bread as a vehicle to spread it on. And seven ounces of mayo?
What in blazes is "yellow cheese"? It looks like the author means yellow American slices for the charred skin on the baked hand meatloaf. Still, they have some artistic ideas, but their recipes do not scream "good cook" to me.
