These cinnamon starts are allegedly THE German Christmas cookie. The vanilla sugar that is required is simply a way of adding a vanilla flavour without using liquid. You can make your own (well in advance) by simply placing a vanilla pod in a jar and filling it with sugar, which after a few weeks will be infused with the spice.
Also known as finikia, these cookies are closely related to Lebanese maakaroun, though the latter are far less elaborate. They are an essential part of a Greek Christmas, but leftovers will comfortably last for a few weeks after, thanks to being soaked in syrup! Do not refrigerate, as that makes them harden.
One of the promises I made regarding this blog is there would NOT be paragraphs of Proustian moments (or dozens of photos) before you can get to the recipe. Instead I give you the root of all Proustian moments — the madeleine itself! Such a lovely little cake, not overly sweet, and very, well, French. It does dry out after the first day, and that makes a big difference, so I only make them for gatherings. Madeleine are usually made in specialized baking tins to give them their scallop shape, but mini cupcake tins work just as well, or use regular-size cupcake tins and underfill them.
