Dragon Fruit and EM/Cotton Candy (TFA) are both 1 drop per 10mL.
This is a delicately complex flavor. The Dragon Fruit may seem like a negligible amount, but it is crucial. Don't even bother trying to make this without it (I did, it was so bland.) The extra layers of sweet and tart in here combine to form excellent tongue excitement!
This is good fresh, but I feel it improves after 1-3 days of steeping. It shouldn't need more than 3 days to reach a nice full flavor.
So as not to lure children into vaping I wanted to repulse them by naming it something gross, like slimy, and indicate that this is a manly adult yogurt. Hence my FDA approved name: Slimy Man Yogurt!
Yogurt base (Sweet Cream 4%, Vanilla Swirl 3%) was suggested by /u/skiddlzninja.
