Rabbi Aryeh Lebowitz

So on that halacha, the Mishra Brura, Tzivkat and Gimel talks about where the Ramah says that if you have vegetables that have air pockets, you need to crush the air pockets to make sure that you get a kazayis of actual vegetable for your kazayis of marar.

So Mishram Brewer says, If there's an air pocket in your matzah, you need to crush the air pocket also, because the air doesn't count toward the gazayis.

Even if your matzah is soft and spongy, but there's no big pocket of air, then you don't need to crush it.

If you have like a sponge cake matzah,

Then you're allowed to use a soft matzah.

It's Maseach Uvituma that you're allowed to use a soft matzah.

He never has a Havamin in that too.

His discussion, B'er Lach, is not to use matzahs less than a tefach.

So suddenly Mishmur disagrees with Rav Shlomo Zalman on this.

One could argue.

One might be able to make that argument.

So Rav Shechter has a tshuva dated Purim Katon Shinas Tavshin Ayin Aleph, where Rav Shechter discusses this issue.

And he points out, The Shulchan Aruch talks about what bracha you make on a cracker.

Like a matzah cracker.

What bracha do you make on a cracker?

So the halacha is a cracker.

You make a mizonos, a brittle piece.

That's one of the definitions possible because it's something that's brittle.

So you would make a mizonos on it, unless you kaveh asud on it.

By Ashkenazim, we always eat matzos that are crackers.
