At Diamond Reef, this frozen Penicillin riff is made in large batches in a Slushie machine, ideal for sipping in the expansive backyard space. This adaptation uses the blender for a similar effect. Note that the peated Scotch is not added to the blender; it’s added at the last minute over the top of the drink.
