cooking kitniyot in a peasdik pot

What is the status of cooking kitniyot in a pot on Pesach (for ashkenazim).
Outside of Israel this is relevant only for small children, sick etc.
In Israel it is relevant this year as to whether one can cook kitniyot on
the 7th day of Pesach for the immediate following shabbat.

All the seforim I have seen pasken that if one cooks kitniyot on Pesach in
a pot then one can either use the pot again for normal Pesach use either
that day or after waiting 24 hours.
I saw one newsletter that claimed that one needs to kasher the pot even for
use the following year !
He further claims that this is the standard custom. I have seen that RHS
allows use the same day. Does anyone know of others who require actually
kashering the pot even if it won't be used until Pesach next year.

Last week, in the thread "Ta'am kitniyos", I wrote that Mishne Berurah
453:7 writes that if a choleh - even a choleh she'AYN bo sakanah - needs
kitniyos on Pesach, one may cook it for him. I was struck by how casually
he said this, yet he said nothing about the keilim involved. So I will now
rephrase the question that I had asked there:

RET referred here to "seforim". Are there actual seforim that discuss this
question? I have seen many publications - usually issued by the hechsherim
- which tell us that kitnios baby food (for example) must be prepared in
separate keilim. But they give no sources. I'd like to see a posek who
tackles this question in writing, and gives his reasoning.

(My wild guess is that if such a source can be found, it is less likely to
be in the context of baby food, and more likely to be in the context of an
Ashkenazi who was invited to eat at a Sephardi home on Pesach.)

Anyone know of such seforim?

Yes! "Medical Halachah for Everyone" [1980, Feldheim] by Abraham S. Abraham
MD, page 82, gives a specific procedure for an Ashkenazi who is suffering
from diarrhea and needs to eat rice on Pesach, and then writes:

Separate utensils must be used for cooking and eating such foods on

Pesach.

His only source for this is Kaf Hachayim 453:27, which opens with:

Regarding keilim which were used for cooking kitniyot, for those who
follow the issur of kitniyot -- after 24 hours they are allowed.

He cites *five* sources on this, but unfortunately, I cannot decipher any
of the rashei teivos (which is par for the course, with me and the Kaf
Hachayim). Then, he discusses at length whether or not a (Ashkenazi) guest
needs to worry if his (Sefardi) host used those keilim in the past 24
hours, and several related situations.

HOWEVER --

I am shocked by how different this halacha appears in Dr Abraham's book,
and in the sefer he cites. I concede that the Kaf Hachayim does cite
several problems that the Ashkenazi should be concerned with, and I concede
that Dr Abraham's procedure safeguards against them all. But it also
conjures up additional problems that the Kaf Hachayim was NOT worried about.

Some might say that I am being too hard on a "kitzur sefer" that tries to
service the layman by packing a lot of information into a few pages. I say:
On the contrary! His book could have been two words shorter if he had left
out the words "and eating". If the kli rishon is okay after 24 hours, I
would imagine that the kli sheni is okay even sooner.

Oh - here's another thing: The Kaf Hachayim was talking about a *healthy*
Ashkenazi who eats from Sefardi keilim. I think that if Dr Abraham is going
to apply those halachos to an Ashkenazi *choleh*, maybe he should cite a
posek on it.

Caveat lector! Check the sources whenever you can!

What if I told you the Kaf Hachayim has an key to rashei teivot at the
beginning of the first volume?

Unfortunately it doesn't help much with ZR', which he already gives two
possibilities for, Zera Avraham and Zera Emet, and I've no idea which Zera
Avraham, but PRH is the Pri Hadash, MHRLNH is R. Levi Ibn Habib, and `RH is
the Erech Hashulhan. That's as far as I can go before Hag!

Hazon Ovadiah on the Haggada (note 8 on page 55 of the 5739 edition) brings
some of the same sources, without so many rashei teivot:

Shu"t Zera Emet helek 3 (helek Orah Hayyim siman 48)
http://hebrewbooks.org/pdfpager.aspx?req=742&st=&pgnum=122
Hukkat Hapesah siman 453
http://hebrewbooks.org/pdfpager.aspx?req=7855&st=&pgnum=172

But as far as I can tell none of the sources are directly addressing the
question of an Ashkenazi cooking kitniot in his own house, as opposed to
being invited to a Sephardi.

I feil to see the problem.

Nosein ta'am and bitul beshishim go hand-in-hand. RMF yses this argument
in a letter to R' Pinechas Teitz to explain why whiskey can be made
in sherry casks; since stam yeinam is batel in only 1:6, there is no
problem of ta'am. You would obviously tased a mixture of 6 parts water
to one part wine. Since qitniyos are batel berov, why would there be
reason to say that a pot can becomes "peasdik"? (To quote a subject
line from a month ago.) Are we afraid that the volume of the walls of
the pot exceed the volume the pot holds?

Tir'u baTov!
