While in Norway last summer I fell hard for a pastry that is very common there, called Wienerbrod. It looks like a cheese Danish, but the white stuff is pastry cream, not cheese, AND there is a filling also--almond paste, much like what you'd find in an almond croissant. Two of my favorite fillings and puff pastry too! I've made a fair imitation using pastry cream and almond croissant filling recipes from Julia Child, and frozen commercial puff pastry. Not a bad likeness, though I need to grind my almonds more finely.
I'll be in Manhattan later this month--anybody know of a bakery that makes this pastry?
