Nitrates serve as preservatives, inhibiting the growth of harmful bacteria, particularly Clostridium botulinum. They also contribute to the characteristic pink color and distinct flavor of cured ham.
The Process of Curing Ham Without Nitrates
Choosing the Right Meat
- Quality Matters: Start with a high-quality, fresh ham. Preferably, choose meat from free-range, organically raised pigs for the best flavor and health benefits.
Preparing the Ham
- Trimming: Trim the ham to your desired shape, removing any excess fat.
- Washing: Rinse the ham thoroughly under cold water.
The Natural Curing Mix
- Salt: Use sea salt or kosher salt as the primary curing agent.
- Sugar: Brown sugar or honey can be added to balance the saltiness.
- Spices: Incorporate spices like black pepper, juniper berries, and bay leaves for flavor.
- Herbs: Fresh herbs like thyme and rosemary add a nice aroma.

The Curing Process
- Mixing the Cure: Combine salt, sugar, and spices in a bowl.
- Applying the Cure: Rub the mixture thoroughly all over the ham.
- Resting: Place the ham in a large container, cover, and refrigerate. The curing time depends on the size of the ham but typically ranges from a few days to a week.
- Turning the Ham: Turn the ham daily to ensure even curing.
Post-Curing Steps
- Rinsing: After curing, rinse off the salt mixture under cold water.
- Drying: Pat the ham dry and let it air-dry in a cool, ventilated area.
To properly dry a ham, it should be patted dry and then placed in a dry curing chamber. This specialized chamber maintains consistent temperature and humidity levels, ideally around 70% humidity and 50-60°F, in a dark environment. Such conditions are crucial for the safe and effective dry curing of meats. It’s important to avoid using unrefrigerated spaces like closets or garages for this process, as they cannot reliably maintain the necessary conditions. Instead, an insulated box with cooling and humidity regulation, such as a modified refrigerator or wine cooler, is recommended to ensure food safety and consistent curing results.

The process of curing ham requires precise control of temperature and humidity. Ideally, the environment should be maintained around 60°F and 60% humidity. To achieve and sustain these conditions, it’s essential to use the right types of humidifiers and dehumidifiers. Let’s delve into what these devices are and the types suited for curing ham.
Humidifiers for Curing Ham
- Ultrasonic Humidifiers: These use ultrasonic vibrations to produce a fine mist, which is then released into the air to increase humidity levels. They are quiet and efficient, making them suitable for small to medium-sized curing spaces.
- Evaporative Humidifiers: These draw air through a wet wick or filter, adding moisture to it before releasing it back into the room. They are effective in maintaining a consistent humidity level and are ideal for larger spaces.
- Steam Vaporizers: These boil water to produce steam, which then cools slightly before leaving the device. They can be very effective but may not be as precise for the subtle adjustments needed in curing environments.
Dehumidifiers for Curing Ham
- Refrigerant Dehumidifiers: These work by drawing air over a refrigerated coil with a fan. The air condenses on the coil and drier air is released back into the room. They are best for higher humidity levels and larger spaces.
- Desiccant Dehumidifiers: These use a desiccant material to absorb moisture from the air. They are particularly effective in maintaining lower humidity levels and work well in smaller, more confined spaces.
- Mini Dehumidifiers: For very small curing chambers, mini dehumidifiers can be a practical choice. They work on the same principles as larger units but are more compact and less powerful.
Choosing the Right Devices
- Size and Capacity: Consider the size of your curing chamber. Larger spaces will require more powerful humidifiers and dehumidifiers.
- Adjustability: Look for devices that allow you to fine-tune the humidity levels. Precise control is key in curing meats.
- Hygrometer Integration: Devices that can be integrated with a hygrometer for automatic humidity control are ideal, as they can maintain the desired conditions without constant manual adjustments.
Tips for Effective Use
- Regular Monitoring: Even with automated systems, regular checks are important to ensure the environment remains stable.
- Maintenance: Keep your humidifiers and dehumidifiers clean to prevent any contamination and ensure efficient operation.
- Placement: Position these devices in a way that allows for even distribution of humidity and temperature throughout the curing space.
In conclusion, the right combination of humidifiers and dehumidifiers is crucial for successfully curing ham. By carefully selecting and effectively utilizing these devices, you can create the ideal environment for producing high-quality cured ham.
