Step by stepInstructions

1. Cream the butter and brown sugar until light, then beat in the egg yolk and vanilla.
2. Stir in the flour, spices, salt, and baking soda until a soft dough forms; add milk by spoonfuls if too dry.
3. Shape into a log, wrap, and chill for at least 1 hour.
4. Slice 1/4 inch (6 mm) thick and arrange on parchment-lined trays.
5. Bake at 350°F (175°C) for 12 minutes until deep golden at the edges.
6. Cool completely — they crisp up as they cool. Store in an airtight tin.
