Yesterday, I had a loaf of pretty much, almost stale bread. Truly, the best way to salvage such a loaf is to cover it in eggs, milk, vanilla and cinnamon. I prepared mine with coconut oil, to give it the additional sweetness from the fry, and enjoyed it will a cup of decaf on my patio. Oh yeah, and I was out of syrup, so I doused those slices in strawberry preserves.
