How to make croutons crunchier throughout without burning?
It's easy to make croutons crunchy: Just dry the bread pieces in a dehydrator or low-temperature oven (around 125&deg;C) for a couple of hours. This should be done before adding oil or seasonings, since the process would cook off a lot of their flavor. Afterwards, drizzle on the olive oil and seasonings, and bake or fry as desired. (Be careful with the oil: the dried bread cubes will absorb it much more quickly than fresh or stale bread cubes would.)
