The moisture of the dressing is a personal preference. Some like it very moist and some prefer it more dry and crumbly. The dryness of the bread also affects how much stock you need, so it can be tricky to get it just right. If your dressing is not moist enough after baking, pour ½ cup of stock over top and let it soak in for 10 minutes before serving. If it's still too dry, add another ½ cup and let it soak in before serving. If the dressing is soggy, you can turn the dressing out onto a sheet pan and cook uncovered at 350°F until it reaches your desired texture.
