During the special Kiddush/Havdallah recited on a Saturday night Chag, acronym Yakneha"z, we make a bracha on the havdalah candle. Normally the Havdalah candle has to be a "torch" consisting of two or more wicks.
Is two wicks required in the Yakneha"z situation? If so, how does one achieve that given the technical difficulties including the Yom Tov prohibition on extinguishing flame.
