I have seen a few people encrust their "used" etrog with cloves and smell this during the havdallah service. Is this permissible?
The reason I think this is a problem:
The bracha on smelling the etrog which is a fruit is הנותן רח טוב בפרות - Who gives a good smell in fruits.
This is an entirely different bracha from the one on the cloves which is בורא מיני בשמים - Who creates varieties of spices. This is the bracha said during havdallah.
From what I can tell, when you smell the clovetrog (no, it's not a kind of monster!) you smell a mix of both the cloves and etrog.
I know that there is a concept of ikar and tafel regarding brachot made prior to eating food. Is there a similar concept regarding the bracha to make for smelling?
In the case of the havdallah bracha, would the cloves be considered ikar, here, and the bracha is finie for the clovetrog? Should one make two brachot? Should one not use the clovetrog at all for havdallah b/c of a doubt of the correct bracha?
Update: I see that there is a M.Y. question that answers which bracha to make on the clovetrog. There are various opinions on this. So, in answering this question, please focus on whether a clovetrog may be used for havdalah. Is there anyone that definitively answers this, or does it strictly depend on which bracha would be made? Or, because of doubts, would it be best not to use this at all for havdallah? (I see many people use it, perhaps, unaware of the "problems".)
