I started with a mini bottle of Chambord, since it's the flashiest one I own. I tied a piece of fishing line around the neck of the bottle and suspended it in my ice-making cooler. I tied the top around a ruler to hold it above the cooler.
Happily it stayed in place while freezing. I popped out the block.
This block was cloudier than usual. I'm not sure if that's because of the object in the ice or not.
It looks a little better close up, so I cut the ice closer to the bottle.
It's not perfect, but it would make a great chunk of ice for a punch bowl.
