One day, for some reason, I went and mixed Soylent 1.8 with Kahlua and Irish cream.... holy cow does it taste good!!
Maybe I'll try with a little bit of rum... but wow! Soylent can cocktail.
We've used this recipe at past events, it's delicious!
What ratio works well? Do you blend in some ice?
I was sort of eyeballing approx equal parts kahlua and cream, then topped the short glass with Soylent. After I drank some, I dashed some more rum to give it a kick.
