I also noticed that people have a tendency to just nibble at sweets after a big meal. Small items had a real appeal. I also was looking for something that was egg-free as a change to offer family and seder guests. For years, I had made a confection-like recipe that called for nothing but soda crackers, butter, and brown sugar. I believe I got the recipe from an old Farm Journal cookbook but noticed others seem to make the same recipe as well.
Some people make a similar recipe using graham crackers.
How logical, how appropriate. Well, the resultant Caramel Matzoh Crunch, aka Matzoh Buttercrunch was an instant hit. It had the perfect one-two punch of ease of preparation and dynamite taste. I probably don't even recall. I wrote many features on Passover - but the Passover Matzoh Buttercrunch became my legendary recipe.
