Boil the half cut yams for about 20 minutes until they become tender.
Let them cool. Then peel them off and slice them into 1/4-inch thickness.
Now combine sugar, salt, flour, cinnamon, nutmeg and grated orange peel.
Take a medium sized casserole dish and place half the yams in it. Now sprinkle with spiced sugar syrup and spread half the margarine over it.
Now add another layer of yams, using the same ingredients as above. Also add orange juice.
Bake it uncovered in an oven, preheated to 350 degree F for about 20 minutes.
Serve it hot.
