Sourdough is a type of bread that has been used since ancient times. It is characterized by its distinctive sour taste, which is caused by the presence of acids produced during the fermentation process. One common question among bakers is whether it is possible to rise sourdough in a metal pan. While some sources claim that the acid in sourdough can react with certain metals and cause negative effects, others argue that this is simply an old myth. In reality, the interaction between sourdough and metal depends on various factors, including the type of metal, the length of exposure, and the acidity of the dough.

What You'll Learn
Sourdough can be baked in a metal pan
Metal loaf pans are perfect for beginners as they give the dough support and create a uniform loaf of bread that's perfect for sandwiches. The size of the pan you use will depend on the recipe, but a 9x4 inch Pullman pan or an 8x5 inch loaf pan will work for most standard sourdough bread recipes.
It is worth noting that sourdough is acidic and can dissolve some metals. However, this depends on the type of metal and the length of exposure. Stainless steel is generally considered safe to use with sourdough, and many bakers use stainless steel bowls, spoons, and scrapers without issue. Other metals, such as copper, brass, and aluminum, should be avoided for long-term storage of sourdough starter as they can react with the acid in the dough and leach toxins.
Overall, baking sourdough in a metal pan is a common and effective method, and with the right precautions, bakers can ensure their sourdough turns out perfectly every time.

Sourdough is acidic and can dissolve some metals
Sourdough is acidic, and it can dissolve some metals. However, the extent of this reaction depends on the type of metal and the duration of exposure.
Stainless steel utensils and containers are generally safe to use with sourdough. They are non-reactive and will not be damaged or discoloured by the acidity of the dough. Many people successfully use stainless steel for mixing, bulk fermenting, and storing their sourdough without any issues.
On the other hand, reactive metals like copper, brass, and aluminium should be avoided for prolonged contact with sourdough. These metals can leach into the dough, potentially causing discolouration and even adding a toxic element to your bread.
It's important to note that the acidity of sourdough is relatively weak and dilute. Therefore, short periods of contact with reactive metals, such as stirring with a metal spoon, are unlikely to cause significant issues.
To summarise, while it is true that sourdough can dissolve some metals, this is not typically a concern when using stainless steel equipment. However, it is recommended to avoid prolonged contact with reactive metals like copper or aluminium to prevent potential issues with your bread or baking equipment.

Stainless steel is safe to use with sourdough
Sourdough is acidic, and it can dissolve some metals. However, stainless steel is safe to use with sourdough. The acid in the sourdough will not react with stainless steel, and no toxins will be leached into the dough. In fact, many bakers routinely start, maintain and feed their starters in stainless steel bowls. Stainless steel utensils, such as spoons, bench scrapers, and bowls, are also commonly used.
While it is safe to use stainless steel with sourdough, it is important to avoid prolonged exposure to other base metals such as copper, brass, or aluminium. The length of exposure matters—short contact with base metals is usually not an issue. It is also worth noting that not all stainless steel is created equal. To ensure the highest quality, look for utensils that are 18/10 or 18/8 stainless steel. These numbers indicate the percentages of chromium and nickel in the stainless steel, with higher numbers denoting greater corrosion resistance.
Some bakers have expressed concerns about the potential reaction between sourdough and metal, but this appears to be an urban legend. Numerous people have successfully baked sourdough in metal tins without any issues. The acids present in sourdough are weak and diluted, and any reaction with stainless steel would be minimal. Furthermore, trace amounts of iron from the metal are likely harmless and may even offer nutritional benefits.
When it comes to baking sourdough, metal loaf pans are recommended over glass or ceramic options. Metal pans, especially aluminium pans, can withstand the high heat required for bread baking, whereas glass or ceramic pans may crack or shatter. Additionally, a metal pan can be placed in the oven during preheating to create steam, which helps produce a golden brown and crispy crust.
In summary, stainless steel is a safe and commonly used material for handling and baking sourdough. Bakers should feel confident using stainless steel bowls, utensils, and pans when working with sourdough, as long as they ensure the steel is of adequate quality.

Base metals should not be used with sourdough
Sourdough is acidic, and it can dissolve some metals. However, the extent of the reaction depends on the type of metal and the length of exposure. While stainless steel is generally safe to use with sourdough, other base metals such as copper, brass, and aluminum should be avoided for prolonged periods. These metals can react with the acidity of the sourdough, causing a toxic leach into the starter and potentially impacting the taste and quality of the bread.
It is important to note that short-term contact with base metals is usually not an issue. For example, stirring sourdough with a metal utensil is generally safe, even if the spoon is made of a reactive metal like tin. However, prolonged exposure, such as storing sourdough in a base metal container, is not recommended.
The myth that metal should not be used with sourdough may have originated from the belief that sourdough starters need to be caught from the air, which is an enduring legend with a long history. Sourdough has been used since before the time of the Pharaohs, and much of its history is from pre-scientific days. However, while sourdough does contain bacteria and yeast that can be present in the air, these are also naturally found in much higher concentrations in the flours used to culture sourdough starters.
Additionally, the type of water used to start and maintain a sourdough starter has been a topic of discussion. Some sources insist that only spring water should be used, claiming that chlorinated water will kill the starter. However, others have successfully used chlorinated water without any issues, as long as it tastes and smells good.
In conclusion, while it is generally safe to use stainless steel with sourdough, it is best to avoid prolonged exposure of sourdough to base metals such as copper, brass, and aluminum. Short-term contact with these metals is usually harmless, but prolonged exposure can cause a chemical reaction that may affect the sourdough negatively.

A water pan can be used to create steam for a crispy crust
Sourdough bread can be baked in a metal pan, contrary to some beliefs that the dough will react with the metal. The acids present in sourdough are weak and dilute, so any reaction would be minimal. In fact, some believe that trace amounts of iron are beneficial to health. Stainless steel containers and utensils are perfectly safe to use, and short contact with base metals is also fine.
There are a few ways to create steam using a water pan. One method is to preheat your oven to 450°F (232°C) and place a pan of hot water on the bottom rack. Bake the loaf for 25 minutes, then remove the pan of water and bake for an additional 15-20 minutes, or until crispy and browned on top. Alternatively, you can preheat a metal pan filled with ice cubes on the bottom rack of your oven. As the ice cubes melt, the water will evaporate into steam, creating a moist environment for your dough, resulting in a crispy crust.
Another technique to create steam is to use a Dutch oven, which traps the water evaporating from the dough and converts it to steam under the lid. This method is considered fail-proof for producing a crispy crust. If you don't have a Dutch oven, you can preheat your oven and baking pan to a temperature 25°F hotter than your recipe, and then use a spray bottle to create steam inside the oven.
