I grew up being served Herring and Chopped Liver.
And they taste just as bad on Tuesday as they do on Shabbos
I never heard of Ptcha until recently, so I asked some of the older generation and they told me why, they HATED it and refused to eat it, even my father who will eat almost anything wont eat Ptcha.
I found it in the store and it did look nasty, Didnt taste that good either unless I heated it up and sopped it up with bread
