NO rice in gołąbki!!! Never ever!
That makes no sense. Gołąbki are essentially a northern version of dolma with cabbage instead of grape leaves. Intermediary versions between Poland and Turkey use fermented cabbage leaves (bulgaria, romania) or cook the gołąbki with sauerkraut (romania, hungary) (presumably to mimic the sour tartness of grape leaves).
Since the original were made with rice I don't see any reason to keep rice out of gołąbki (though barley or buckwheat might make more regional sense).
