Where in Militia-gan do you live? You can at least get some speculaas at Meijer. My personal favorite, which may be more of a Dutch-American thing is butterletter (boterleter?). Sometimes it's just called the generic, "banket." It's a pastry filled with almond paste. If anyone has ever had a Good Humor toasted almond ice cream bar they have an idea of what the flavor is like.
