Making stroopwafels with a pizelle iron
I did some reading and checked several recipes. First, while all pizelle irons cook thin waffles, there does appear to be a difference in thickness from one iron to another.

From the recipes I looked at, the following information and suggestions were given:


In order split the pizelles in half, you must split them immediately upon removal from the iron, before they have had a chance to harden.
If your pizelle iron makes the thinnest waffles and it is impossible to split them you can put the filling between two waffles.


Also, regarding the comments about the hardness of stroopwafels, it seems that it is customary to sit them on top of a hot cup of coffee or tea for some seconds to soften them.

I haven't had the opportunity to try these but they sound delicious. I may try my hand at them soon. :)
