The Black Widow is Blavod Vodka's answer to a Cape Codder. It, quite simply, opts for the black vodka in this straightforward vodka-cranberry drink, which adds an eerie effect that is perfect for Halloween parties.
If Blavod is not your vodka of choice or you cannot find it, you can always make your own black vodka using whichever brand you prefer. It's a very easy trick that you can learn how to do yourself.
There are also two ways to construct the drink. One is to float the vodka on top of the cranberry, which may not always work if you go with the DIY black vodka. The second option is to create a swirling cloud of black vodka by drizzling it into the juice. With either option, the effect will be lost once the drink is stirred, but it is a fun look for a few minutes.
