The reason we dry bread cubes is to remove excess moisture, which helps the bread hold its shape and prevents it from becoming a soggy mess when you mix it with other ingredients. It's like when you dry your hair after a shower - you want it to be nice and fluffy, not dripping wet. Same idea with bread cubes!
Now, you might be wondering, how do I dry bread cubes? It's actually pretty easy - just cut the bread into cubes, toss them on a baking sheet, and pop them in a low-temperature oven (like 200-250°F) for a few hours. You can also use a dehydrator if you're feeling fancy. The result is perfectly dry bread cubes that are ready to soak up all the flavors of your stuffing.

But, why is this process so important? Well, when you use fresh bread, it can be too moist and fall apart when you mix it with other ingredients. By drying the bread cubes, you get a better texture and a more even distribution of flavors. It's like the difference between a soggy sponge and a crunchy crouton - which one would you rather have in your stuffing?
