Example Input: [header] How to defrost bread [title] Thaw out as many slices as you'll need. [step] If you're only going to use a portion of your sliced bread, it's best to defrost that portion only.

Set aside as many slices as you'll need to defrost and save the rest in the freezer. (B) It shouldn't take more than 1 hour. [title] Squeeze from a plastic bag if you don't have a plastic bag.
