Preparation

• Preheat oven to 375 degrees.
  Grease an 8-inch baking dish and set aside. If using strawberries, slice in halves. Place berries in a large bowl.
  In a small bowl, using a fork, stir sugar with cornstarch until blended. Add to berries along with rum and orange peel. Stir gently until mixed. Turn into prepared baking dish and spread out evenly.
  Topping:
  Using a fork, stir flour with baking powder, lime peel, salt and sugar. Cut shortening into flour mixture until it resembles oatmeal.
  Make a well in dry ingredients and pour in milk. Mix just until a wet dough forms. Do not overmix.
  Drop spoonfuls of dough randomly on top of berry mixture. Use back of a spoon to spread a little dough just over open spaces.
  Sprinkle dough evenly with brown sugar. Place baking dish on a baking sheet to catch any drips.
  Bake until topping is golden and cooked through, from 50 to 55 minutes. Insert a skewer into centre of cobbler. If it comes out fairly clean except for berries, it is done.
