Cocoa shell

The papery husk blown away during winnowing. Long treated as waste, increasingly brewed as an infusion.

What it is

Every kilogram of nib comes with a shell that winnowing removes, and for most of industrial history it was a by-product used for garden mulch or animal feed. Its use as an infusion — steeped like tea, producing a light, faintly chocolatey drink with very little fat — has grown alongside the craft sector's general interest in using more of the pod.

It matters to the rest of the catalogue for a less appetising reason too: shell left in the nib is gritty, tastes woody and papery, and does not grind out. The efficiency of a maker's winnowing is a real quality variable, and it is one of the hardest things to do well at small scale.

What the percentage means here

Not applicable. Cocoa shell is a single component and carries no cacao percentage.

Working with it

Steeped in hot water or milk for an infusion. Contains theobromine, so the usual caution about chocolate and dogs applies to shell mulch in a garden as well.

  • Cocoa products and petsCocoa shell sold as garden mulch retains theobromine, and it is the exposure people least expect because it is not food and is not in the kitchen.
  • Chocolate and horsesCocoa husk in feed manufacture is the realistic exposure route for a horse, and the one behind theobromine findings in competition animals that have never seen a chocolate bar.
