Black currant liqueur, also known as “crème de cassis” is a rich ruby elixir with an intense sweet-tart flavor. Serve slightly chilled in little cordial glasses or shot glasses, any time of the day or night. -Or- make a kir, kir royale, or communard. Lovely drizzled over fresh berries and vanilla bean ice cream. And, would be very pretty decanted into pretty bottles to give as gifts during the holiday season. A must try if you have access to fresh black currants, but would also be good made with fresh red currants. From Martha Stewart "Living" July, 2003. Note: This is a two week process, and the yield is my guess.
