Spekulatius is a wonderful highly spiced German Christmas cookie. It's very thin (approx 1/8 inch). Buttery and crumbly crisp. Reminiscent of gingerbread but actually I think rather more refined and usually has a few flaked almonds across the top although I have also seen them with glace cherries or both. I'm searching online for a good recipe and this is one of the ones that I've come across that looks like it should give the correct taste and result - although I haven't baked it yet due to time restrictions. As with many cookies it seems that it is important to keep the dough cool during kneading. Note that the almond flakes on the top should not be broken up. The resulting cookie should be very hard and wonderfully butter-crispy.
