Suggestions for homemade boysenberry liqueur

[Tzatziki]

I got gifted something like a dozen quarts of fresh-picked boysenberries last month (my friend has like an acre of them on her property, so lucky...), and I've been soaking some of them in vodka for the past month and a half to make a liqueur. It's starting to taste pretty good!

 

I'm thinking that it will probably work well with any recipe that calls for creme de cassis, but I'm wondering if anyone has played around with boysenberries in cocktails before and has any unexpected suggestions! Thoughts?

For the liqueur, I'd try a Bramble.  Or a Kir Royale if you like that sort of thing.

 

I'd also drizzle it over vanilla ice cream, maybe with some sliced stone fruit. Peachs and Cassis are fabulous this way.
