Found in the Toronto Star. Adapted from Jewish Cooking for All Seasons. The tester tried this recipe using different types of apples (Crispin, Honeycrisp, Empire, Golden Delicious) and recommends Crispin (Mutsu) and Honeycrisp.
An apple corer may be used rather than a melon baller. You'll have a smaller hole that cuts right through the apples and you'll be able to stuff more apples.
