There is nothing like candied yams. We always have them on holidays so it's a treat for me because my husband only likes white potatoes. My mom used to make them anytime we had pork of any kind and this is her recipe.
Place yams in a baking dish, reserving juice. Add juice to a med sauce pan. Add in the stick of butter and brown sugar. Stir until it comes to a boil Add in the crushed pineapple and juice to make 1/2 cup. Bring to another boil, reduce heat and simmer for 10 minutes. Pour syrup over yams and top with raisins and pecans if you like. Bake in a 350 degrees oven for one hour. Baste occasionally with the juice.
