Laser cut gingerbread
It's Christmas and I know it is possible to laser cut gingerbread so I thought I might as well give it a try. Eli and I made a batch from the BBC recipe and he rolled it all flat using some 6mm ply as guides for the rolling pin. The bread expanded to 10mm thick and I drew some shapes for the laser. We went really slowly 2 passes at 10mm/s @ 80W and on the second pass could see smoke coming out the honeycomb so knew it had cut through. We were left with this intricate snowflake 10cm across and a rather nice negative of it too. (svg here)
