Measure your recipe’s intended loaf pan size (or the batter fill level) and compare to the substitute’s interior dimensions.
Line the substitute: parchment bottom + “sling” overhang for easy lift, then lightly grease to help it stay in place.
Start baking at the low end of the recipe’s time, then check doneness with a toothpick/thermometer (center should come out clean).
If the top browns too fast, tent loosely with foil; if the center is underdone, bake in 5-minute increments.
Cool 10–15 minutes before lifting out; for denser loaves, cool longer to prevent breakage.
