How to Ferment Mortadella
Mastering Traditional Italian Sausage Techniques
Mortadella is a traditional Italian sausage originating from Bologna, celebrated for its delicate flavor and meticulous crafting process. One of the cornerstones of Italian charcuterie, mortadella is easily recognizable by its sizeable, cylindrical shape and dotted appearance from the cubes of pork fat within. Unlike some of its cured counterparts, mortadella is not fermented but rather a cooked sausage, often mistaken for being fermented due to its rich flavor and aroma that result from a complex blend of spices and slow cooking. The recipe, which has been passed down through generations, embodies the essence of Italian culinary art.
The crafting of mortadella follows a precise recipe. High-quality pork, punctuated with cubes of pure white fat, is ground and then seasoned with a harmonious mix of salt, spices, and sometimes wine or garlic, to infuse the meat with an aromatic depth. These seasonings are carefully selected to complement the natural flavors of the pork without overpowering them, showcasing the balance that Italian cuisine is renowned for. The ground meat is then stuffed into casings and cooked in a water bath, ensuring that the sausage retains moisture and achieves a smooth, homogenous texture.
The resulting product is a testament to the expertise of Italian sausage making. Mortadella's smooth texture and distinctive taste make it a versatile ingredient, enjoyed on its own or used to elevate an array of dishes. It serves not only as a culinary delight but also as a cultural symbol, preserving a piece of Italian heritage within its savory slices.
History and Tradition
The origins of Mortadella trace back to the Roman Empire, where records in Latin detail a product remarkably similar to the modern sausage called "farciemen mirtatum." Over the centuries, Mortadella solidified its reputation as a cherished Italian meat, specifically within the city of Bologna, earning its name from the Latin word "myrtatum," which means seasoned with myrtle berries.
Traditionally, Mortadella is a type of salumi, a term encompassing Italian cured meat products. It stood out because of its unique use of heat-cured pork and the inclusion of visible cubes of white fat, typically from the throat of the pig. Bologna, the Italian city, is so intrinsically linked to Mortadella that the sausage often carries the name Mortadella Bologna.
In 1998, the European Union recognized the cultural and historical significance of Mortadella Bologna, granting it a Protected Geographical Indication (PGI). This status is reserved for products inherently associated with a geographical location, necessitating adherence to traditional production methods and ingredients, including:

Fermenting and Curing Process
When fermenting and curing Mortadella, precision in salting, maintaining correct temperature and humidity, and using the right starter cultures are critical for developing the right flavor and texture.
Salting and Curing
To begin the curing process, kosher salt is evenly distributed throughout the ground meat mixture, which often includes a blend of pork and fatback. The salt performs several key functions: it draws out moisture, creates an inhospitable environment for harmful bacteria, and enhances the meat's flavor. For Mortadella, the meat is often seasoned with spices in addition to the salt, such as garlic, black pepper, and coriander.
Temperature and Humidity Control
The temperature and humidity levels during fermentation and curing are vital. Initially, Mortadella is fermented at a higher temperature, typically around 85°F (29.4°C), to encourage the growth of beneficial bacteria. This stage usually lasts 24 to 48 hours. Then, the temperature is lowered for the drying phase. A controlled humidity level, generally around 80% to 85%, ensures that the sausage dries evenly without the exterior becoming too hard before the interior has fully cured.
The Role of Starter Cultures
Starter cultures, consisting of Lactobacillus and Pediococcus species, are introduced to kickstart the fermentation and acidification of the meat. These cultures convert sugars into lactic acid, which lowers the sausage's internal pH, preventing spoilage and developing the tangy flavor characteristic of cured meats (What wine goes well with cured meats?). They also contribute to the firm texture and longevity of the finished Mortadella.
Cooking Techniques
Before fermenting, mortadella must be cooked properly to reach the right consistency and flavor. Cooking also ensures safety by bringing the internal temperature of the sausage to a level that eliminates harmful bacteria.
The Boiling Method
The boiling method involves cooking mortadella in a water bath. Sausages are traditionally submerged in hot water maintained just below boiling point. The key to this technique is maintaining a consistent water temperature, typically between 75°C to 85°C (165°F to 185°F), to cook mortadella thoroughly without splitting the casing.
Steps to boil mortadella:
Preheat water in a large pot to the desired temperature.
Gently place the sausage into the water, ensuring it is fully submerged.
Cook until the internal temperature of the mortadella reaches at least 68°C (154°F).
Once cooked, place the mortadella in an ice water bath to cease the cooking process and stabilize its shape.
Using Sous Vide
Sous vide is a precise cooking technique that involves vacuum-sealing mortadella in a bag and submerging it in a water bath at a controlled temperature. This method enhances flavor and texture by cooking the sausage evenly and retaining its moisture.
Steps for sous vide cooking:
Set the sous vide machine to a specific temperature, commonly around 68°C (154°F).
Vacuum-seal the mortadella in a sous vide bag, ensuring no air pockets remain.
Place the bag in the water bath and cook for a predetermined time based on the sausage's size to achieve the perfect internal temp.
After cooking, remove the sausage from the bag and, if desired, quickly sear it in a hot pan for a caramelized exterior.
By adhering to these precise cooking techniques, the mortadella is prepared at an optimal temperature for successful fermentation.
