Steam the
couscous for half an hour until it is really soft. Stir in the butter and
sugar first and then the rest of the ingredients. Decorate with a walnut.
Grate the rind form 1 orange and
press the juice from both. Add enough water to make one ample cup, add the peel
and bring this to the boil. Pour over the couscous and let it stand for half an
hour. Stir in the other ingredients.
