Melt shortening and butter together and allow to cool.. Add brown sugar, carrots and beaten eggs. Sift all dry ingredients together before adding to wet ingredients. Mix till just blended.
Sprinkle a well greased 7" (six cup) ring mold with plain bread crumbs (Panko would work). Put batter into ring mold and bake at 350 for about 45 minutes or until nicely browned. Should be served slightly warm.
