Man… sometimes you just need some existential contemplation while ponderously crunching ice flavored heavily of coffee, drenched in a creamy flavor, and backed up by the liberating aspects of a good vodka. Therefore, after trial and error, I bring you The Dude’s favorite beverage cast into a vegan form. Polymorphed, if you will, but not transmogrified.
It’s simple, man. Instead of cream, use Silk soy-milk. It is, like, thicker than other soy-milks so it makes that creamy goodness that is enjoyable in a white russian. My preferred mix is 1:1*, coffee liqueur to vodka, and then put in whatever amount of Silk I want which is usually at least twice the mixed amount.
Remember not to drink and adventure. And, above all, remember… The Dude abides.
