Ingredients
Method
- Mix the dry ingredients: In a large bowl, whisk together the rice flour, potato starch, tapioca starch, xanthan gum (or psyllium), baking powder, salt, ground almonds, brown sugar, vanilla sugar and all five spices. Rub any lumps of brown sugar between your fingers so the spices spread evenly.

- Rub in the butter: Add the cold butter cubes and rub them into the dry mix with your fingertips until it looks like coarse, sandy crumbs and no big pieces of butter are left.

- Bring the dough together and chill: Add the egg (and the vanilla extract, if you use it instead of vanilla sugar) and knead briefly, just until the dough holds together. Only if it stays crumbly, add milk a teaspoon at a time: the dough should be firm, not sticky. Press it into a flat disc, wrap it and chill for at least 1 hour, or overnight.

- Shape with a mould or a cutter: Heat the oven to 175 °C top and bottom heat (160 °C fan, 350 °F) and line two baking trays with baking paper. With a Spekulatius mould: dust the carved side with potato starch and tap out the excess, press a piece of dough firmly into it and trim it level with a knife, then knock the edge of the mould firmly on the worktop until the biscuit drops out, and set it on the tray. With a cutter: roll the dough between two sheets of baking paper to 3 to 4 mm and cut out shapes; a cookie stamp or an embossed rolling pin still gives you a pattern. Press flaked almonds onto the backs if you like. If the dough gets soft, chill the shaped biscuits on the tray for 10 minutes.

- Bake: Bake for 10 to 12 minutes, until the edges turn light golden; small or thin biscuits are done sooner. Leave them on the tray for 5 minutes.

- Cool and store: Lift them onto a wire rack and let them cool completely: they come out of the oven soft and turn crisp as they cool. Keep them in an airtight tin, apart from soft cookies, for about 2 weeks.

Notes
• Flours and starches: rice flour, potato starch and tapioca starch contain no gluten, but buy packs labelled gluten-free, because some are packed where wheat is handled. Using a ready-made gluten-free flour blend instead? Check its label too, and if it already contains xanthan gum, add none.
• Baking powder: most use a corn, potato or rice starch filler, but some use wheat flour or wheat starch. In the EU and UK wheat is named on the label; one labelled gluten-free settles it.
• Ground almonds: almonds contain no gluten, but some are processed where wheat is handled. Choose packs with a gluten-free claim.
• Spices: pure single ground spices are gluten-free, and pre-packed is the easier choice than loose spices from a bulk bin. If you use a ready-made Spekulatius spice mix instead (about 1 tbsp), read the label: blends sometimes use wheat flour or wheat starch as a filler.
• Xanthan gum or psyllium, vanilla sugar, flaked almonds: read the labels too.
• Icing sugar, if you dust them to serve: it sometimes contains an anti-caking starch, usually corn or potato. Read the label.
• Your mould: dust it with potato starch, never with ordinary flour. If it has been used for wheat dough, flour sits deep in the carvings: brush it out and wash it well, or keep one mould just for gluten-free baking.
• Contains almonds, egg and milk: worth saying when you share them.
• When a label is unclear, treat it as "not for me". Swaps
• Binder: 1 tsp xanthan gum or 1 level tsp psyllium husk powder, never both.
• Vanilla: 1 tsp vanilla sugar or ½ tsp vanilla extract.
• Nut-free: leave out the ground almonds and use 50 g more of the flour blend; the biscuits will be a little firmer. Storage
• Keep them in an airtight tin for about 2 weeks, apart from soft cookies such as Zimtsterne, so they stay crisp. For gluten-free baking, weigh if you can: cups vary a lot with these flours.
