Washing hands for eating pizza

Question

How many slices are required to make you responsible to wash on Pizza?

Answer 1

Some kashrus orgnazations require apple juice in dough not all

Answer 2

I thought that commonly pizza dough in the US was made mezzonot(so that one would need to eat the necessary shiur to pass into it being considered a meal).

Whereas pizza dough in E"Y is typically made as lehem and thus one slice needs washing.

Answer 3

The answer in this shiur too:

Brachos Shiur -Rabbi Viner

Answer 4

Please refer to the final halacha in b'tzias hapas. The Shulchan Aruch rules that pashtida (dough filled with various fillings including meat, fish or cheese) is hamotzi even as a snack. The Mishna Berurah distinguishes this from pas haba'a b'kisnin in that the latter is mainly baked as a treat whereas pashtida is eaten for satiation. He says it's no different than a meat sandwich You just put the meat on before baking, but the intent is the same. I will let the reader opine for himself where pizza falls in.

Answer 5

Rabbi Jachter suggests, based on a Biur Halacha, that the amount required for washing should vary based on gender and age. The money quote:

"It should be noted that the Biur Halacha (168b s.v. Af Al Pi) asserts that the “objective standard” varies from group to group. He specifically mentions a distinction between young and old people. Thus, if an older individual plans to eat an amount of Pat Habaah BeKisnin that most older people consider to constitute a meal, he must recite Hamotzi even though a younger person would view that amount of food as merely a snack. Rav Daniel Wolf of Yeshivat Har Etzion (Yeshivat Har Etzion’s Daf Kesher volume 6) suggests that a distinction can be made between men and women regarding this matter, as men generally eat more than women. I have often wondered whether adolescent boys should be considered as a distinct group regarding this matter as well, since they tend to eat more than most other people. Personally speaking, I considered three slices of pizza to constitute a meal when I was a teenager, and as an adult I consider two slices of pizza to constitute a meal."

Answer 6

1. The opinion of Harav Moshe Feinstein zt”l holds two slices makes you responsible to wash.(I believe this would be the Main Psak (Halachic Ruling) for American's)

2. Harav Shlomo Zalman Aurbach zt”l, and Harav Elyashiv say one slice of Pizza since it has 8-9 k’zaysim it would require one to wash and bentch.

3. Rav Belsky Shlita Rosh Yeshiva of Torah Voddas and Posek for the Orthodox Union says
   two slices would only be a meal if they are eaten with something else, such as a knish. While I personally ascribe to 3 each person should seek Rabbinical counsel for this and all other question.

Square otherwise known as Sicilian pizza which is made by first baking the dough and then adding the cheese is always Hamotzei the same applies to Pita-Pizza made by taking a Pita and putting cheese and Ketchup on it the Bracha also maintains it's Hamotzie status.
