Suppose someone finds themselves with no candle to do Havdolah with. He neither has a Havdolah candle nor two candles in which to put together and light. What should he do?
I would assume he would recite Havdolah like normal, only omitting the brocha of borei m'orei ho'eish but then again I could very well be wrong.
What about the similar case of not having any spices to smell?
