Gray color and liquid on my dough: Is there something wrong?

Return to FAQs page

As your dough stores in the refrigerator, it might develop a uniform gray discoloration and liquid on its surface.  This is not mold and can be safely ignored– it won’t affect the final baked result. You can just pour off the liquid and proceed with the recipe.

If you see patchy light or dark areas on your dough, whether smooth or fuzzy, that could be mold and the dough should be discarded. You are not likely to see mold if you follow our directions for maximum storage life, and keep the dough in the refrigerator.

If the dough has become hard and leathery, that suggests that there’s too much air-space in your container (or that it isn’t sealed well enough).  You can decrease the effect of air that gets into the container by transferring into smaller containers as the dough is getting used up.

  1. Can I do something to revitalize “older than two weeks old dough” and still be able to use it? I used 3+ weeks old dough, and it did not rise very well. Good flavor, though.

    • Hi Phillip,

      How much dough is left? Best thing to do is to add the “old” dough to a new batch to jump start the flavor of the new. Just mix the water with the old dough and then make the dough as normal. Blending the old dough and water with an immersion blender is the fastest way.

      Thanks, Zoë

      • Hello, Ma’am.

        Thank you for your note back to me. I had exactly enough dough left over to make one loaf.

        I am more grateful for your guidance. It sounds like a “winner” to me.

        I have enjoyed your book very much. I have read it through three times. Good stuff!

        Thank you.

        I was stationed in Sicily for 3 years recently, and travelled throughout Europe. I got so used to their breads. Yum.

  2. I make my dough for noodles one day, wrap in saran wrap, put it in the fridge and the next day when I go to use it, it has turned a dark color. What is wrong??? Thank You

  3. I have begun making my own greek yogurt and everyone says to use the whey that I strain in my bread. Can whey be substituted to water in the master recipe from your first book?

    • I’ve done it and I like the result– there’s a more sour flavor, see if you like it. Lot’s of nutrition in that whey.

  4. I had made homemade bagels from a recipe on pinterest. the recipe called for the bagels to proof overnight in the fridge. the recipe called to oil the parchement paper. I had no other oil other than olive oil so i lightly misted the parchement paper. the next morning i began boiling the bagels and noticed “green spots” on the bottom of the bagel dough when i flipped them during boiling. Is this just dye from the olive oil or did mold happen overnight??? thanks.

  5. Hi why does my freshly pizza dough get grey bits on the bottom and when I cook it , it turns into mould is its because I freeze it

  6. Thank you so much for this wonderful book about Artisan Bread! I have not been able to get the bread from the peel to the hot stone without having to scrap it off the peel with a spatula. Is there a proper amount of corn meal or flour that is supposed to be used? Maybe I am scrimping so that I don’t have smoke to deal with. Thanks, Stephanie

    • Hi Stephanie,

      The best insurance to get the loaf off the peel is to set it on parchment. You just slide the parchment and loaf right onto the stone and bake it. No mess in the oven and it never sticks! If you like the flavor of the cornmeal on the bottom crust, just dust the parchment with cornmeal before placing the dough on it.

      Enjoy, Zoë

  7. The New Artisan Bread in Five: Master recipe

    I typically use King Arthur flour for your recipes. However, my local grocery store had a sale on Gold Metal flour, so I decided to purchase a few bags. During the process of making a few batch’s of bread with the Gold Metal, everything seemed the same. But, when we would cut into the loafs after they are cooked and cooled, we are noticing that the crumb is a darker color and kind of gray inside. Is this due to the difference in the flour?

    I used the same storage tubs, same utensils and same measurements as what is defined in the book. I made the dough two separate occasions, once the dough was refrigerated overnight before initial use, the next batch was refrigerated for 3-4 days before making a loaf. Any ideas why the crumb is dark and kind of gray looking?

    P.S. My husband bought me a Danish dough whisk for Christmas. My family loves all the recipes we have tried thus far. :-)

    • Hi Deb,

      My initial thought was that the batch might be a bit older, and it can sometimes turn gray, especially if the container is tightly closed. However, you mentioned that you got this result from a fresh batch. Did you notice any liquid on the top of the dough or was it particularly dry?

      Thanks, Zoë

      • Hi Zoe,

        It wasn’t the actual dough that looked gray, it was the interior crumb after it was baked that looked gray.

        There was no liquid at the top of the dough, and the dough wasn’t particularly dry. However, come to think of it, while I was shaping the loafs, I used more flour than typical in an effort to keep it from sticking to my hands. Could it be that I incorporated too much flour while making the gluten cloak? Could that cause the interior crumb to be gray?

        Thanks in advance for your response.

        Deb

      • Hi Deb,

        This gray coloring is really only something I’ve experienced with a dough that has been stored for a week or more in the refrigerator. I’ve never experienced it with fresh dough made from unbleached KAF or Gold Medal. Is the flour you bought bleached or unbleached?

        The only other thing I can think of is that something reactive came into contact with the dough, like a metal spoon that may turn the dough gray?

        Thanks, Zoë

      • Oh boy….well….I checked the bags of flour and noticed that I accidentally bought “bleached” flour. (I never buy bleached flour, I always buy unbleached.)

        So would the fact that the flour is bleached cause the crumb to be gray?

        I did buy a baking steel and have been baking my bread on parchment paper over the baking steel. But since I am baking it on parchment paper, I wouldn’t think that would cause the grey color.

      • Hi Deb,

        I bake on a steel too and love it, that’s not going to cause a reaction even if you bake directly on the steel. I think it is the bleached flour. The unbleached flour has a creamy color to it, which is what you are used to. The bleaching will make it whiter, or in this case a bit gray, but there is nothing harmful in the bread, just the difference in color.

        Thanks, Zoë

      • This may not be a very kosher thing to do, but I live alone and I don’t have to bake bread all that often for myself.

        When it is time to bake a new loaf,and I find that my dough is “too old to rise again,” I take it out of my plastic dough container, flour it some, and roll it out “really thin” on my kitchen counter.

        I take a tablespoon of new yeast and dissolve it in only two tablespoons of warm water. I let it dissolve, and then stir it.

        I then pour the yeast solution all over the rolled-out dough and let it soak in for a few moments. I then roll up the dough and knead it for only about a minute, until it seems like the new yeast mixture has been completely absorbed into the dough.

        I then put the dough back in its container and let it rise until it flattens on top. Then it goes into the refrigerator overnight.

        The next day, I follow your “standard operating procedures,” to form, rise, and bake the loaf.

        It works great, and I don’t waste any dough at all. Plus, I get the beginnings of some great sour dough taste.

        Phil

      • Hi Philip,

        This sounds like a great solution. We typically would use that last little bit of dough to “seed” the next batch of dough with that sour dough flavor. Just dump the new ingredients over the old dough and mix as normal.

        Cheers, Zoë

      • Thanks for your reply about the color. My husband and kids actually noticed a taste difference between the bleached and unbleached. We felt it did not taste as good. It could all be in our head, but we have decided to return the unopened bag of bleached flower. They were on sale buy one get one free right before the holidays, so I just grabbed without really reading. Lesson learned. Thanks again for helping me to tease apart what happened. I appreciate your efforts.
