I'm trying a recipe that requires cubed stale bread, but it's too hard to cut! I already tried wrapping it in a damp towel and microwaving it, but that only softens the crust.
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
The damp towel and microwave should really do it. Try sealing the damp towel covered loaf in a plastic bag for a few hours. Keeping it air tight should make the moisture move more throughout the whole loaf.
If this doesn't work, do you have a sharp serrated knife? You'd be surprised what one could cut through.
Thanks, I did that and then put it in the oven for ~10 minutes and it did the trick! (I do have a serrated knife, but not of great quality, so even my boyfriend wasn't able to do much with it.)
