Does anyone know how to make it.
These are a bit more Polish specific.
I made quite a lot last year. Remember that ones made with spirytus and then diluted down tend to turn out better than ones with vodka (Bimber works
very well in a nalewka recipe), the fruit must be
clean and dry, and do not, repeat not, use plastic bottles. That can be dangerous.
Jagoda and Wiśnia seem to work best. Coffee and (expensive) chocolate is less authentic but very good.
There are lots of recipes though and people often have their favourite.
edit:
I just saw Piorun's post, and it's very similar to one I made that really worked well, though everyone said to leave it in the dark, away from the sun. Worth trying, and I agree about the cherry stones.
