Redcurrant - it's the same as blackberry, but more acid and healthy! 

ちゃま I'm not sure that customs will let me, but I'll try to bring it (sure not homemade) in my next arrive to Japan! I hope you can try! Or there is another way - come to Moscow !

Ashita Oh~,Sunao-san likes it! I will try it if I have a chance.

ちゃま yes, it looks.. but it's very acid... It's tasty in MORS, traditional Russian non alcohol drink made from different berries. Sunao likes it D He wrote it in blog after visiting Russia.

Ashita It looks good & delicious!
