Mix this together in a small bowl. It should be kind of thick and gloopy. Don’t put on the glasses until ready to serve.
For the drink:
Place the raspberries in a small bowl and use a fork to mash them until very well broken down.
Put them in a cocktail shaker, add the remaining ingredients, and shake about 10 seconds.
Take a silicon spatula and apply a thin layer of raspberry blood around the rims.
Strain the drink into the prepared glasses. If using dry ice, please read all the safety tips first and then add a chunk of dry ice to the cocktail. Let the dry ice dissolve before drinking.
