You can use either fresh or frozen cranberries in this recipe. If using frozen you don’t have to defrost them, but I recommend rinsing off any ice crystals if present.
It is important to decide the texture you will want for your sauce. That will vary the cook time. If you want the apples to still hold their structure, cook the sauce for less time. If you want all of the ingredients to blend together and form an actual sauce, cook it for more time.
