Troubleshooting: Gummy, Dense, or Flat
Okay. This lesson's a little different. We're not adding a new skill, we're going back through everything and figuring out what went wrong when it did, because it will. Every baker has a shelf of ugly loaves somewhere in their history. Mine started with a hockey puck.
That first real loaf I baked, I was so proud of myself for even getting the dough shaped right. Pulled it out of the oven, let it cool like you're supposed to, cut into it, and the middle was gummy and dense and it hadn't risen hardly at all. I about gave up right there. Took me a while to figure out what happened: my water was too cold when I mixed the dough, and our dry air out here crusted the surface over before the dough ever got a real chance to proof. It looked fine on the outside. Looked like bread. Cut it open and it was a brick with a crust glued on top.
So let's go through the big three complaints and what's usually causing them, because nine times out of ten it traces back to one of a few things.
Gummy crumb
This is the one that scares people most because it looks undercooked, and sometimes it is. But gummy isn't always a baking problem, it's often a fermentation or moisture problem.
Most common cause: underbaked. If your loaf came out of the oven under 205°F internal, it's not done, full stop. I've said this before but I'll say it again here because it matters: get an instant-read thermometer, it's ten dollars, don't guess. Push it into the center. 205 to 210 is your target. If you pulled it early because the crust looked dark enough, that's the mistake. Crust color and doneness are two different things, especially in a hot Dutch oven.
Second cause: cut too soon. Even a fully baked loaf will look gummy if you slice into it while it's still steaming hot. The crumb structure is still setting. I know waiting an hour for bread to cool feels ridiculous when the whole house smells like that, but give it at least 45 minutes, an hour's better. This one's on you to just be patient, and I say that as someone who is bad at patience herself.
Third cause: too much water, not enough structure. If your dough was very high hydration and your gluten development wasn't quite there yet, you can get a slack, wet crumb that never really firms up right even after a full bake. If this keeps happening, back off five percent hydration next time and see if it tightens up.
Dense, tight crumb, no rise
This is my hockey puck problem, basically.
Cold water, cold room, cold everything. If your water's too cold going into the mix, or your kitchen's sitting at 65 degrees in January, your starter and your dough are both working in slow motion. Fermentation barely happens, so there's no gas built up to make the crumb open. This is exactly why we built the proofing tote a few lessons back. Use it. I didn't have one my first year and I paid for it with pucks.
Starter wasn't ready. If you mixed your dough with a starter that hadn't peaked yet, or worse, one that had already fallen back down, there isn't enough active yeast in there to do the job. Float test it before you commit. If it sinks, wait.
Underproofed dough. Dense can also mean you moved to shaping and baking too early in bulk fermentation. Dough that hasn't risen enough just doesn't have anywhere to go in the oven.
Now here's my honest opinion on this, and it's a little contrarian: I would still rather see a slightly dense, under-fermented loaf than a gummy, over-fermented one. Everybody's chasing that big open holey crumb you see online, and they push fermentation right up to the edge trying to get it, and a lot of them fall off that edge into a gummy mess that won't slice. A loaf that's a hair underproofed still tastes like bread and cuts into a clean slice you can make a sandwich with. That's just me, but I'll take the safe miss over the risky one every time.
Flat loaf, spread out instead of up
Overproofed. This is the opposite problem from dense. If your dough overfermented, the gluten structure basically gave out before it hit the oven, and instead of holding a dome shape it just slumps sideways. Check your bulk ferment timing against room temp, and if you're running warm, pull it earlier next time.
Weak shaping. If your final shape wasn't tight enough, there's not enough surface tension to hold the dome through the oven spring. Go back to the shaping lesson and really work that surface taut.
Oven not hot enough at the start. A big blast of heat right at the beginning is what drives the oven spring. If your oven wasn't fully preheated, or your Dutch oven wasn't hot when the dough went in, you lose that first push and the loaf just kind of sits there and spreads instead of jumping up.
One safety note while we're in here: if you're chasing a hotter oven to fix a flat loaf, don't go overboard. I overbaked a batch once chasing a darker crust and set the smoke alarm off at my own house with a room full of people. Told them straight, that one's on me, my oven runs hot and I should've watched it closer instead of trusting the timer. Push your oven temp up in small steps, and watch it, don't just walk away and hope.
Before next time
Think back through your last loaf or two and see if you can place it in one of these categories. Bring your notes on what you think went wrong, and we'll troubleshoot it together before we move on.
