Traditionally, I've only seen round Matzos at the Passover Seder table, those being know as Shmura Matzos.  Both round & square are sold in my local but only the square is available all year long. My inner whiner says that either shape has historically had the same effect on my digestive system year after year.
 
Bill, I totaly agree; OY VEY IS MEER!!  NICHT GUT FER MINE KISHKE.

You can find the Hollandia brand here in the Netherlands all year long and in most supermarkets, but only the round version.

If you're in the Netherlands all you need are stroopwafel.
 
I'm convinced.  Pretty easy to polish off a couple dozen of those babies over coffee.
 
Hard to find in the states, and that's probably a good thing.

Stroopwafels are supposed to be the #1 Dutch delicacy that every tourist gets hooked on instantly, but I have a thing against caramel overdoses.

Was ist kishke?  Mein Deutch ist nicht gut.

As the activists say, do you really expect us to swallow that tripe?
