Can I substitute frozen cranberries for fresh, and should they be thawed before folding into the batter?
Yes—frozen cranberries work just as well as fresh. Fold them into the batter straight from the freezer (do not thaw) to prevent excess juice from turning the crumb pink; the loaf may need an extra 2–3 minutes of bake time.
How should I store the cooled loaf, and can it be frozen without compromising texture?
Once the glaze has set, wrap the loaf tightly in plastic (or place in an airtight container) and keep it at room temperature for up to 3 days, or refrigerate for 5. For longer storage, double-wrap the whole loaf or individual slices in plastic and foil, freeze for up to 2 months, and thaw at room temperature while still wrapped—the crumb stays moist and the glaze holds up well.
Can I bake the batter as muffins instead of a loaf, and how should I adjust the baking time?
Yes—divide the batter among a lined 12-cup muffin tin, filling each well about ¾ full, and keep the oven at 350°F. Standard muffins will bake in roughly 18–22 minutes (mini muffins 12–14 minutes); start checking when the tops are domed and a tester inserted in the center comes out clean. Cool in the pan 5 minutes, then transfer to a rack before glazing.
