cocktail help?

this is a super weird request, and I will totally get if no one can help but I figured reddit is good for this type of shit lol

so I’ve been on vacation this past week and I had gone to the Goldfinch Tavern/Bar…? in Seattle for a drink before a tour and I can NOT STOP THINKING ABOUT THIS COCKTAIL.

It was called Purple Rain and it had pineapple, blackberry, vanilla, and lemon w/ vodka but obviously I don’t know the amounts for the liquids and I really want to try recreating this cocktail at home. If anyone is like a crazy master mixologist or happened to work at Goldfinch and has made it, please let me know the amounts….. that shit was so good and I can’t stop thinking about it.
