Place almonds and orange zest into Thermomix bowl and mill for 10 seconds on speed 9.
Add cocoa, sugar, salt and flour and mill for a further 10 seconds on speed 9.

Place chocolate into Thermomix bowl and chop for 5 seconds on speed 8.
Melt for 2 minutes at 37oC on speed 2.

Place onto baking trays and cook for 6 minutes at 200oC.
They should be crisp on the outside and chewy in the middle, though the thinner the dough, the less chew factor!
