12 ounces chocolate syrup
This is not an infusion, but rather a solution. You just mix the vodka with some chocolate syrup. As such, it's ready to use as soon as it's mixed together.
It's everything you expect: sweet, chocolaty, syrupy. I'd like to figure out how to separate out some of the solids and leave it clearer and cleaner in the mouth.
I've heard of others who infuse vodka with pieces of chocolate. I am assuming that the pieces of chocolate eventually dissolve into the vodka and so what results is still a solution. I might try that to see if it yields a less muddy result.
I am also curious to figure out how to filter this stuff. It pours right through a wire strainer, but immediately stops when I try to pour it through a coffee filter or cloth. Suggestions are appreciated.
