Great idea! Looks wonderful with a little extra work. After making this several times in anticipation of a "Witches Brew and Frightful Finger Foods" cocktail party, I have perfected the best way to approach this "Brain Dip" recipe.
Heat water until it reaches a slow/ gentle boil. Set cauliflower face down carefully into the center of your boiling pot with enough water that it envelopes 90% of the cauliflower, but leaves the stem showing. The stem should be out of the water.... On a slow rolling bowl (approximately 10 -15 minutes depending on size of cauliflower) blanch the head of cauliflower until it is barely soft - this makes "carving" out the cauliflower much easier.... Let the cauliflower cool until it is warm and then hollow out the center. So much easier than other reviewers have noted!
I found the "veins" to be equally time consuming - either adding the fruit or "painting" the veins with food coloring! Either way, the end result is magnificent. Hat's off to you Annie1 for creativity and ingenuity. Thanks for a guaranteed recipe to provoke a discussion, comment or a second look for a fun filled and spooky holiday!
