Gammon, that delectable cured pork often enjoyed during holidays and special occasions, can be a source of culinary confusion. One of the most frequently asked questions surrounding its preparation is: do I need to boil gammon before roasting? The answer, as with many cooking inquiries, isn’t a simple yes or no. It depends on several factors, and this comprehensive guide will walk you through them all, ensuring a perfectly cooked and flavorful gammon every time.
Understanding Gammon: The Basics
Before diving into the boiling question, let’s establish a solid understanding of what gammon actually is. Gammon is essentially a cured leg of pork. The curing process involves brining the pork, which infuses it with salt and other flavorings, preserving it and giving it its distinctive taste. Once cooked, gammon becomes ham. So, technically, you’re roasting gammon to create ham. The crucial difference lies in the cooking process.
Different types of gammon exist, each with varying levels of saltiness and intensity of cure. You’ll typically find it sold raw (requiring cooking) or pre-cooked (ready to eat). This article focuses primarily on raw gammon.
The Great Boiling Debate: Pros and Cons
The decision to boil gammon before roasting is a pivotal one. It influences the final texture, flavor, and saltiness of the meat. Let’s examine the arguments for and against this technique.
Arguments for Boiling Gammon
One of the main reasons people boil gammon is to reduce its saltiness. The curing process can leave the meat quite salty, and boiling leaches out some of this excess salt, resulting in a more palatable final product. How much salt is leached is subjective and depends on the curing process and how long the gammon is boiled.
Boiling also helps to tenderize the gammon. The long, slow cooking in water breaks down the tough muscle fibers, resulting in a more succulent and easier-to-carve ham. This is especially important for larger joints of gammon. The heat changes the protein structure of the meat which is critical to tenderizing the gammon.
Finally, boiling can impart additional flavor to the gammon. You can add aromatics like bay leaves, peppercorns, cloves, onions, and carrots to the boiling water, infusing the meat with subtle and complementary flavors.
Arguments Against Boiling Gammon
Conversely, boiling can also have some drawbacks. One significant concern is that it can wash away some of the inherent flavor of the gammon. While you can add aromatics, some argue that boiling dilutes the pork’s natural taste.
Another potential issue is that boiling can result in a less appealing texture. Over-boiled gammon can become somewhat watery and mushy, losing its firm and satisfying bite. It may be difficult to achieve a consistent texture when boiling.
Some argue that boiling doesn’t improve the flavor. You may be able to achieve the same or better result by roasting the gammon directly. Boiling can be a time-consuming process.
Factors to Consider Before Deciding
So, how do you decide whether to boil your gammon before roasting? Here are some key factors to take into account:
Salt Content
The saltiness of the gammon is the most important factor. If you know your gammon is heavily cured or you’ve purchased it from a source known for salty meats, boiling is likely a good idea. If you’re unsure, you can try a small sliver of the raw gammon to assess its saltiness. The salt content is one of the biggest reasons home cooks choose to boil.
Gammon Size
Larger gammon joints benefit more from boiling. The longer cooking time ensures that the heat penetrates all the way to the center, resulting in a more evenly cooked and tender product. Smaller joints may not require boiling, as they cook through more quickly in the oven.
Desired Texture
Consider your preferred texture. If you prefer a very tender, almost fall-apart gammon, boiling is a good option. If you prefer a firmer texture with a slightly drier bite, roasting without boiling might be better.
Flavor Preferences
Think about the flavors you want to achieve. If you want to infuse the gammon with additional flavors through the boiling liquid, then boil away. If you prefer the pure, unadulterated flavor of the cured pork, then skip the boiling step.
Boiling Gammon: A Step-by-Step Guide
If you’ve decided to boil your gammon, here’s a detailed guide to help you through the process:
- Rinse the Gammon: Start by thoroughly rinsing the gammon under cold running water to remove any excess salt or brine.
- Choose a Pot: Select a pot large enough to completely submerge the gammon. Ensure it has a lid to help maintain a consistent temperature.
- Add Aromatics (Optional): Place the gammon in the pot and add your desired aromatics. Common choices include bay leaves, peppercorns, cloves, halved onions, and carrots.
- Cover with Water: Pour cold water over the gammon until it’s completely submerged.
- Bring to a Boil: Bring the water to a boil over high heat. Once boiling, reduce the heat to a simmer.
- Simmer Gently: Cover the pot and simmer gently for the appropriate amount of time. A general rule of thumb is to simmer for 20 minutes per pound (450g) of gammon. Use a kitchen timer to keep track.
- Check for Doneness: After the simmering time, use a meat thermometer to check the internal temperature. The gammon should reach an internal temperature of at least 160°F (71°C).
- Cool Slightly: Carefully remove the gammon from the pot and let it cool slightly before handling. Discard the boiling liquid.
Roasting Gammon: The Finishing Touch
Whether you’ve boiled your gammon or not, roasting is the final step in creating a delicious ham. Roasting allows you to develop a beautiful, caramelized crust and further enhance the flavor.
- Preheat the Oven: Preheat your oven to 350°F (175°C).
- Prepare the Gammon: If you’ve boiled the gammon, pat it dry with paper towels. Remove the rind, leaving a thin layer of fat. Score the fat in a diamond pattern. This will help it crisp up during roasting.
- Glaze (Optional): Apply a glaze to the gammon. Popular choices include honey, maple syrup, brown sugar, mustard, and fruit preserves. The glaze is critical to creating the outer crust.
- Roast: Place the gammon in a roasting pan and roast for 15-20 minutes per pound (450g), or until the internal temperature reaches 170°F (77°C). Baste the gammon with the glaze every 15-20 minutes to keep it moist and flavorful.
- Rest: Remove the gammon from the oven and let it rest for at least 15-20 minutes before carving. This allows the juices to redistribute, resulting in a more tender and flavorful ham.
- Carve and Serve: Carve the gammon thinly against the grain and serve.
Alternatives to Boiling: Other Methods for Desalting
If you’re concerned about the potential drawbacks of boiling, there are other methods you can use to reduce the saltiness of gammon:
Soaking
Soaking the gammon in cold water for several hours, or even overnight, can help draw out some of the salt. Change the water several times during the soaking process for best results.
Poaching
Poaching is similar to boiling, but it involves simmering the gammon at a lower temperature. This gentler method may help reduce the risk of overcooking and drying out the meat.
Direct Roasting with Basting
Roasting the gammon directly, without any prior boiling or soaking, can also be successful. Basting the gammon frequently with water or stock during roasting can help to draw out some of the salt and keep the meat moist.
Troubleshooting Common Gammon Cooking Issues
Even with the best intentions, things can sometimes go wrong. Here are some common gammon cooking issues and how to address them:
Gammon is Too Salty
If your gammon is too salty after cooking, try serving it with accompaniments that can help balance the saltiness, such as sweet chutneys, tangy relishes, or creamy sauces. You can also shred and add to mac and cheese, or use in soups or stews.
Gammon is Dry
Dry gammon is often the result of overcooking. Use a meat thermometer to ensure you don’t overcook the gammon. Basting frequently during roasting can also help keep the meat moist.
Glaze is Burning
If your glaze is burning during roasting, reduce the oven temperature or cover the gammon loosely with foil.
Gammon is Unevenly Cooked
Unevenly cooked gammon can occur if the gammon is not properly positioned in the oven or if the oven temperature is not consistent. Use an oven thermometer to ensure your oven is accurately calibrated. Rotate the gammon during cooking to ensure even cooking.

By understanding the pros and cons of boiling, considering the factors that influence the outcome, and following the detailed steps outlined in this guide, you can confidently prepare a perfectly cooked and flavorful gammon that will impress your family and friends. Remember, taste as you go, adjust the cooking time as needed, and don’t be afraid to experiment to find the method that works best for you. The goal is a delicious and memorable gammon experience.
Why is boiling gammon before roasting sometimes recommended?
Boiling gammon before roasting is often recommended primarily to reduce the salt content. Gammon is cured pork leg, and the curing process typically involves a significant amount of salt. Boiling helps to draw out a portion of this salt, resulting in a more palatable and less intensely salty final dish, especially if you prefer a milder flavour.
Secondly, boiling can help to pre-cook the gammon and make it more tender. This is particularly useful for larger gammons or if you’re aiming for a specific texture. Boiling ensures the gammon is cooked through evenly before roasting, preventing it from drying out while the outside develops a beautiful glaze and colour in the oven.
What are the pros and cons of boiling gammon before roasting?
The main advantage of boiling is salt reduction and achieving a more even cooking. By simmering the gammon, you remove excess salt, making it more suitable for those sensitive to sodium. Furthermore, pre-cooking ensures the interior reaches the desired temperature before roasting, preventing a dry or unevenly cooked result.
However, boiling can also leach out some of the flavour from the gammon. Additionally, it adds an extra step and time to the cooking process. The texture can also become slightly less firm compared to roasting directly from raw, though this can be managed with careful timing.
How long should I boil gammon before roasting?
The boiling time depends on the size and weight of the gammon joint. A general rule of thumb is to boil for approximately 20 minutes per pound (450g) plus an additional 20 minutes. For example, a 4lb (1.8kg) gammon would need to be boiled for around 1 hour and 40 minutes.
It’s crucial to ensure the gammon is fully submerged in water during the boiling process. You can add aromatics like bay leaves, peppercorns, or cloves to the water to infuse the gammon with flavour. Always start with cold water to allow the salt to leach out gradually and evenly.
Can I roast gammon without boiling it first?
Yes, you can absolutely roast gammon without boiling it first, especially if you prefer a saltier flavour and are comfortable with a potentially longer cooking time. This method often results in a richer, more intense pork flavour, as none of the natural juices or salts are leached out through boiling.
When roasting gammon from raw, it’s essential to monitor the internal temperature carefully using a meat thermometer. Ensure the thickest part of the gammon reaches a safe internal temperature of at least 145°F (63°C) to ensure it is cooked through. This will likely take longer than if you boiled it beforehand, so plan accordingly.
What liquids can I use for boiling gammon other than water?
While water is the most common liquid for boiling gammon, you can use other liquids to infuse it with extra flavour. Consider using stock, cider, or even a combination of water and apple juice. These additions can subtly alter the gammon’s taste, adding depth and complexity.
Another popular option is to use cola (full-sugar varieties work best). The cola’s sweetness and spices impart a unique flavour to the gammon, creating a delicious glaze when it’s roasted afterwards. Just be mindful of the increased sweetness in the final product when choosing your liquid.
How do I know when the gammon is cooked after boiling and before roasting?
After boiling, the gammon should feel slightly firm but yield slightly when pressed. The internal temperature should be close to the safe cooking temperature, but you don’t need to reach the final target yet, as it will continue to cook during the roasting process.
A simple test is to insert a skewer or small knife into the centre of the gammon. If it goes in easily with little resistance, it’s likely cooked enough for the boiling stage. Remember, the roasting stage will finish the cooking process and add colour and flavour.
How do I prepare the gammon for roasting after boiling?
After boiling, carefully remove the gammon from the pot and allow it to cool slightly before handling. Pat the gammon dry with kitchen paper to remove any excess moisture. This will help the glaze adhere properly during roasting.
Score the fat in a diamond pattern, being careful not to cut into the meat itself. This allows the fat to render and crisp up during roasting, creating a beautiful and flavourful crust. Apply your chosen glaze, ensuring it covers the entire surface of the gammon, and you’re ready to roast.
