Q. Regarding the minhag not to eats nuts during the aseret yemei teshuva (because the gematria of egoz is the same as that of cheit), to which nuts does this actually apply?
Walnuts are called Egozei Melech.
Hazelnuts are called Egozei Luz.
Almonds are called shekeidim.
Pecans are called Pecanim.
Etc.
To which nuts does this minhag actually apply?
Thanks, and ktiva vchatima tova.
A. Horav Shlomo Miller's Shlit'a opinion is that all nuts that are known as or named egoz, even when they have an additional name, would qualify to be included in the minhag of not eating them on Rosh Hashana.
