Youngberries are a complex hybrid of raspberries, blackberries and dewberries. I saw youngberry juice at the grocery store today and thought it would make a nice margarita. The berry flavour is surprisingly delicate given its progenitors so I added some lime and Cointreau to add depth.
1 1/2 oz good quality tequila
2 oz youngberry juice
1/2 to 1 oz freshly squeezed lime juice
1/2 oz Cointreau
