Wash the chestnuts thoroughly. Place them in a large bowl and cover them with water. Leave to soak overnight.

Next day remove any loose pieces of skin. Preserve water for boiling the chestnuts. A pressure cooker will save much of the cooking time. Follow instructions given with pressure cooker. in any case allow to boil until tender.

Add the other ingredients and continue cooking for about half an hour. If the stew is still watery at this stage reduce it by further cooking. Finally taste for sweetness and add more cocoa, if necessary. Serve hot.
