That’s a shame… but you didn’t know.
Yes, there are lots of Dutch communities in Canada the US and other countries. If there is a shop. This will be a staple in it.
The brand doesn’t really matter as long as it is the thick sticky sirupy one. Very sweet.

You could even make it without the peperkoek, but Appelstroop should be in it.
Without peperkoek you need something to thicken the sauce… neutral flavoured. Than just add some spices like ginger, nutmeg, extra cloves etc.
