The best part about this recipe is that it’s incredibly delicious AND it’s super simple. Just blend all the ingredients in a food processor, pour into a brain mold and freeze. It doesn’t get any easier than that. Especially if you’re throwing a party, it’s great recipe to make ahead of time. But beside all that practical stuff, for me, the really fun part was plating and styling this easy appetizer for our mad scientist theme. Mad scientist’s are always messing around with body parts to create monsters and hybrids beings. So I just had to make this super cool brain scanner that started with an old speaker that I picked up from the thrift store for next to nothing. I added some odds and ends from around the house. and tada! Check out easy recipe and how to make the brain scanner prop video below. Enjoy!
