Maybe I could get the recipe you used for the Expedition Star cookies you brought to Prague? (I'm assuming that you use the British term "biscuits" to mean the sweet, crunchy baked goods Americans call "cookies" because they inherited the term from the Dutch.) If it's handy, please feel free to share it on the recipe thread.
Yes, for me as a french person, a cookie is a special sort of biscuits with tiny bits of chocolate inside
I can share the recipe, I'll just have to translate it... or maybe you'll find an other but I know the one I'm using give a good result. It's a Christmas's biscuit from Austria called zimtsterne (cinnamon's stars), so might be a problem for persons who don't like cinnamon. (I had never try to bake them without the spice but it might be possible with all the almond powder inside...)
