Black currant (aka Cassis) soda, juice, or concentrate.

[CloggieGirl]

I grew up with black currant soda called (among other things) Cassis. It also came in a concentrated syrup that you could add to water or seltzer. Recently, I've had a strong craving for it but haven't found any yet. Anyone have any pointers? I'll take any form I can find it in to easy my winter blues.

Sahadi's on Atlantic Avenue (between Court and Clinton St) in Brooklyn has a wide variety of syrups, including black currant. Their prices are great and overall selection of all things delicious is very impressive.

IKEA sells a Black Currant sparkling juice, I think it is Kristian Regale, Swedish or something. It's pretty good.

Fairway carries several Black Currant drinks- including Ribena. I like "Premium Fresh Black Currant" by Philicon. They have a lot of juice flavors, but this one diluted with seltzer makes a great Cassis soda.

Ribena concentrate can be found in Manhattan Chinatown supermarkets.

Schaller & Weber on 2nd Ave neare 86th St carries the concentrates, and so does the Hungarian Market on 2nd Ave near 81st.

I see ribena concentrate in Chinese supermarkets (Chinatown and Flushing) all the time. Myers in Greenwich Village has it too.

Zabar's has many flavored syrups, including casis - brand: Monin - in the room with the coffee.

Incidentally, Clinton Winery in upstate New York makes a lovely dessert wine of black currant. It has a beautiful bouquet and rich berry flavor, natural sweetness (not cloying).

Last but not least, Kee's Chocolate makes a wonderful cassis macaroon. You will surely find many ways to satisfy your craving in NY.
