Rabbi Aryeh Lebowitz

You don't have anything to bake with.

You can buy flour from the marketplace and make matzah, just make something, bake it quickly, under 18 minutes.

You could do that b'dyavid b'dyavid.

We don't pass it that way.

If you buy flour nowadays from the supermarket, you're buying chametz.

That's chametz gomer because we have pre-washed flours.

That's in terms of the levels of supervision.

So, okay, so you've got to eat Shmura Matzah.

When must you eat Shmura Matzah?

So at the Seder, it's very obvious, very clear, that in order to fulfill the mitzvah of eating Matzah, you need Shmura Matzah.

Whether it be machine or hand, whatever it is, you need Shmura Matzah at the Seder.

What about the rest of Pesach?

So the Torah certainly says we have to be careful not to eat chametz the rest of Pesach.

But what about Matzah that was made v'shma throughout the rest of the days of Pesach?

So, on the simplest level,

The mitzvah of Achilles matzah is only on the first night.

After the rest of Pesach, there's Nisr Hametz, there's no mitzvah of Achilles matzah, so there should be no reason to have to eat matzah that was made l'shma, Shmurah matzah for the rest of Pesach.

So why is it that some people are makvid, that they only eat Shmurah matzah for the rest of Pesach?

So the Be'er Lacha quotes from the Vilna Gaon that the Vilna Gaon only ate Shmura Matzah throughout Pesach because he was concerned that water might have fallen onto the grain during some step of the process and it would be a problem of Chameitz.

That was really a concern of Chimeitz.
