If you haven’t heard of it, try it. It smells wonderful and tastes just as delicious. I found it while wandering through a shop called Sasha’s International Market in San Antonio, Texas. The market has Eastern European food/drinks with a focus on Russian specialties (the shop will have its own post on my blog).
Tarragon is used medicinally as well cooking, and is definitely my favorite herb. When I read “tarragon” and it looked like a liquid I got so excited. The idea of tarragon soda was invented in Georgia (the country), and is very popular in Russia, and other Eastern European countries.
I personally have never seen this offered in any grocery store, though maybe I haven’t looked hard enough.
