You can use any type of pear you want in this recipe, including Bosc, Anjou or Bartlett. You can also switch altogether and use apples or a combination of apples and pears! Whether or not you peel the fruit is entirely a matter of personal preference, but it will not affect the recipe. Crystalized ginger is found in the baking section of most stores, but if you can’t find it, you can substitute 2 teaspoons of freshly grated ginger.
