To prepare a spiced blackberry pear and apple pavlova recipe, first you need to gather your ingredients. First, you'll need blackberries, pears, and apples. You can find them at your local farmer's market, or you can buy them online. If you don't want to buy apples, just use any type of apple you like. Then, mix the ingredients together until they're well-combined. Next, pour the mixture into the prepared pan and bake it in the oven for 40 to 45 minutes, until the top is golden brown and the filling is set.
