Simanim on Rosh Hashana

All the ones mentioned in the gemara and shulchan aruch. Why would I leave any out or add any extra?

“Why would I leave any out ”
Lots of reasons maybe it isnt your minhag, particularly as we dont know with certainty what they are (particularly “rubyia”)

“or add any extra?”
the MAgen Avrohom famously mentions adding based on other languages such as Carrots which are “mehren” in Yiddish (means multiply similar to Rubya) .

I also add farfel and say “Unzer soin’im zol farfallen veren.”

I don’t think there is such thing as a minhag not to do something mentioned in the gemara and shulchan aruch without any machlokes. What happened is that some of the items mentioned were not availabe in Europe in previous generations, so they had to do without, This does not constitute a minhag, and there is no doubt that nowadays everyone should eat all the simanim that are obtainable.

The carrots were a substitute for the unavailable rubiya, because it had the SAME meaning in yiddish, but there is no indication that one should search for NEW meanings and simanim in ones current vernacular.

If you’re creative with your puns, there is almost no limit to the amount of “simanim” you can make up.
Here are some you might like:
Soup – for a super year
Mayonnaise – Hashem should open for us the wellsprings (ma’ayonos) of wisdom etc.
kiwi – As the pasuk says “ki vi yirbu yamecha etc.
apple – we should live appley ever after
lettuce – let us have a good year
raisins and celery – mentioned by iacisrmma above
liver – Hashem should de-liver as from harm

“I don’t think there is such thing as a minhag not to do something mentioned in the gemara and shulchan aruch without any machlokes”

I’m not sure what you mean there are countless examples.
The first one that pops into my head : The Gemara says the Haftorah for Simchas Torah is Shlomo’s birchas Hamelech there is no machlokes in the Gemara. I am certain that isnt what your shul lains.

“there is no doubt that nowadays everyone should eat all the simanim that are obtainable.”
There is doubt. First and foremost because we arent sure what they all are.

“The carrots were a substitute for the unavailable rubiya, because it had the SAME meaning in yiddish”
ok, but this isnt brought in the Gemara nor shulchan aruch

You’re right about there being things in the gemara, I guess my main point was the fact that it is in the shulchan aruch and poskim without any dissenting opinions among the rishonim. As far as I know it is a clear historical fact that the so called “minhag” not to eat some of the simanim was simply born of neccessity and thus does not constitute a valid halachic minhag.

The only siman whose identity is in any real doubt is rubiya. If this fact induces you to substitute carrots, be my guest. That’s not what I was talking about.

What I am saying is:
a) Don’t miss anything out just because your grandfather couldn’t get hold of it.
b) Making up your own simanim is cute, but don’t feel obliged to eat something just because your grandfather happened to be fond of a particular pun.

1. I disagree with both of your premises. We practice what our Grandfathers did.
“as far as I know it is a clear historical fact that the so called “minhag”…” Many minhagim are like that. do you opose using a spoon feather and candle to search for chametz? (yes theres a differecne between doing and not doing)
2. I am not saying you should stop eating it or that there is an issur. I am just answering your original question “Why would I leave any out ” IT could be becasue your family doesnt eat a paricular one, It could be because you dont know what it is, it could be becasue you dont like it.
Are you saying there is a chiyuv to eat each of the simanim? I suppose that would mean a kezayis of each, (ain achilah pachos mikezayis) do you have extra shiurim cards for all of the simanim?

“Making up your own simanim is cute”
Thats what the OP wanted,
You provided a few thanks
Though for Liver some chasidim eat becasue “Leib ehrlich” (yiddish for liver – live righetously)
OF course there are other simanim tat Rebbes ate. See nitei Gavriel and the book “Rosh hashana secrets”
