If your dough feels dense and tough to handle when you stop the mixer, it is a sign that it is becoming over-kneaded. Over-kneaded dough can become very hard to work with and produce a more flat and chewy bread.
Loaves made with over-kneaded dough often end up with a rock-hard crust and a dense, dry interior. Slices will be very crumbly, especially toward the middle.
Knead dough by hand for 15-20 minutes: Knead 5-10 minutes at a time, taking breaks in between. Avoid using a mixer for the kneading process, which can heat up the dough too much and may not activate the gluten in the flour effectively. If using a mixer, always knead the last five minutes by hand.
You can tell you've kneaded dough too much if it becomes difficult to stretch. Sometimes this happens when you use a stand mixer or food processor. Overkneaded dough will be tough and make tough, chewy bread.
And given enough time, a machine can begin to break down gluten by mechanically breaking the bonds between gluten proteins. An overmixed dough becomes slack, lacks elasticity, and can't hold its shape at all.
Overproofed is when the dough has rested too long and the yeast has continued making carbon dioxide while the strength of the dough (gluten bonds) have begun to wear out. The dough will look very puffy, but when you touch it or move it you may notice it deflate or sag.
The dough will rise slowly overnight or up to 24 hours. Allowing the dough to remain longer in the refrigerator isn't beneficial, as an extended time in the refrigerator will lead to off flavors and diminished dough strength.
You most definitely can bulk ferment sourdough too long. If you leave the dough to ferment for too long, it will become "over fermented". Over fermented dough will lose its structure and become a soupy, sloppy mess that you will not be able to shape.
Ideally, you don't want to allow sourdough bread to cold ferment for longer than 72 hours. Even up to 48 hours, you do risk some loss of gluten structure unless you manipulate the amount of starter down.
Well, sourdough is a stickier, wetter dough than regular yeasted bread. This is mainly because sourdough is higher hydration, meaning it contains more water. While sourdough is a wetter, stickier dough than what you may be used to, it should still be able to be stretched, folded and shaped without too many issues.
What causes sticky sourdough or bread dough? Overly sticky dough is normally caused by a combination of using the wrong flour and using too much water. I discuss these points in more detail above but in short: choose a flour that's produced for bread baking. These are normally labelled “Bread” or “Strong” flour.
The Poke Test – Give that ball of dough a firm poke with your finger. If the indentation fills back quickly, you're good to go. If it stays looking like a deep dimple, continue kneading.
If: The dough pops back out quickly – This means its under-proofed. The dough stays where it is – This means its over-proofed. The dough pops back out slowly and leaves a slight indentation – Perfect, your dough is ready!
Resting the dough gives the gluten structure a chance to loosen and unwind, and it will give you a better final product.
The crumb structure of an under proofed loaf will be tight and gummy. Because it was not given enough time to develop and trap CO2 gasses, the crumb structure will be very dense, with uneven air bubbles.
Most recipes call for three or four rounds of stretch and folds, repeated every 20 minutes or so. What is this? By the last round, the dough should keep its shape, and not feel as sticky as it did at the start. It may also have small bubbles on the surface depending on the recipe.
If your recipe calls for more than 227g (about 1 cup) of starter, feed it without discarding until you've reached the amount you need (plus 113g to keep and feed again).
Let rest in a warm spot to rise. The dough is ready when it no longer looks dense and has doubled in size. This can take anywhere from 3-12 hours depending on the temperature of your ingredients, the potency of your starter and surrounding environment.
We've actually left our bread in the refrigerator for up to 18 hours with no problems. When you're ready to bake, remove the shaped dough from the refrigerator and let it sit on the counter while your oven preheats. Place it in the dutch oven, score it, and bake as usual.
Sourdough bread can be time consuming to make, and it can be difficult to fit it all in in just one day. Leaving it to rise in the fridge overnight means you can just pop it into the oven the next morning. This can be handy if you don't want to spend all day in the kitchen, or simply need to go out during the day.
Dough that is over-fermented will start to spread once scored and look bubbly/weak. You'll notice it falling in a bit or a lot. Notice how the whole loaf is collapsing. If you notice your dough is over-fermented be sure to score very shallow and use a minimum of scoring slashes.
Some types of crumb include: fool's crumb (a mix of very tight and big holes), honeycomb or lacy (evenly spaced and moderately open), and wild (a mix of moderate and very large holes).
The crumb should be light and fluffy - not wet and gummy. The holes inside the sourdough may seem shiny. This is a sign that the gluten is very well developed.
The good news: We found an easy way to rescue overproofed dough. Simply punch it down gently, reshape it, and let it proof again for the recommended amount of time. In the test kitchen, these steps resulted in bread that tasters found acceptable in both texture and flavor.
