You could omit the frozen tart cherries here and use other fruits instead-perhaps blackberries and nectarines, or peaches and raspberries.

The book calls for tart sweet cherries which may require more than ⅔ cup of sugar. I almost always use frozen dark sweet, so ⅔ cup is plenty. Also, if you are using dark sweet cherries in place of tart, you may want to (I always do) add at least a tablespoon of fresh lemon juice.
