Nice combination. There is a citrus sourness upfront that finishes with a nice raspberry finish. Interestingly, I did not find this cocktail overly sweet as posted in the comments, and I am not partial to sweet drinks. Very nice combination of citrus and berries. I will agree though that this fits better in a Nick and Nora glass than a standard shot glass.
I wanted to like this shot, but it won't fit in a standard shot glass. Gonna experiment with the proportions.
Definitely too sweet for a shot. Here's what I like so far.... (and will fit in a shot glass): 1oz Vodka, 1/2oz Lime juice, 1 Bar spoon (~.15oz) Simple syrup, 1 Bar spoon (~.15oz) Black raspberry liqueur
