This recipe works well with peaches or fresh sour cherries as well.
Heat oven to 400 degrees. Butter a 12 X 7 baking dish; add plums. Mix 1/4 cup sugar, tapioca and orange juice.
Drizzle over fruit.
Mix flour, baking power and sugar into a medium bowl. Add shortening and cut in finely. Stir in coconut and orange rind.
Add milk and mix lightly with fork to make a soft, puffy dough.Knead gently. Roll or pat into an oblong slightly smaller than baking dish and cut into 6 squares. Lay squares over fruit. Cut a small slash in centre of each and sprinkle lightly with sugar.
Bake until topping is nicely browned and fruit is bubbling; about 25 minutes.
