This is one of those instances when you smack your forehead with the palm of your hand while muttering, "Why didn't I think of it first?"
And then you realize that you're not as much of a culinary genius as you thought you were, and this brilliant dessert had to come from someone who is. And that would be Chef Einat Admony.
Though a bit time consuming, what with the matzo soaking and syrup making and nut shelling and chopping (plus, this is a plan-ahead treat that likes to sit for two days), it's actually not that difficult to prepare.
I switched up the 1 tsp of rose water for 1 tbsp orange water just because I prefer the taste, and doubled the cinnamon, but besides that, it worked like a tasty charm.
