In ordinary British shop use, gammon is cured pork sold uncooked; ham is sold ready to eat. Not every ready-to-eat ham is cooked, so read the actual label.
The difference at a glance
In ordinary British shop use, gammon is cured pork sold uncooked and needing cooking; ham is sold ready to eat. Both can come from the pig’s hind leg. Cooking a gammon joint turns it into ham in everyday language, but not every ready-to-eat ham is cooked: some hams are dry-cured. [1] [2]
The useful distinction is the product’s preparation and readiness, rather than two different animals or an automatic quality ranking. Here, the starting comparison is an uncooked gammon joint or steak versus ham sold for eating straight away.
| Feature | Gammon | Ham |
|---|---|---|
| Usual state when bought | Cured but uncooked; cooking is required. [1] [2] | Ready to eat, whether cooked or sold as a ready-cured product. [1] [2] |
| Shared origin | Normally hind-leg pork. [1] | Can be made from the same cut. [2] |
| Smoking | Available smoked or unsmoked; that does not remove the cooking step. [1] | Read the actual preparation description; smoked and cooked describe different processes. [1] [2] |
| Immediate use | Not an uncooked substitute for sandwich ham. [1] [2] | A product labelled ready to eat suits a no-cooking use. [1] [2] |
| What happens after cooking? | A cooked joint becomes ham in ordinary terminology. [1] [2] | Cooked ham has already reached that preparation stage. [2] |
| Shared practical check | Follow the instructions for that joint or steak. [3] | Check whether the product is ready to eat and any instructions for its intended use. [1] [3] |
Gammon is cured, usually by dry-salting or brining, and can also be smoked. Cured does not mean cooked: the gammon in this retail comparison still requires cooking. A smoked label tells you about that treatment, not that an uncooked joint is ready for your sandwich. [1]
The word ham is broader than “boiled gammon”. Ready-to-eat dry-cured hams are part of the category too. That is why “gammon is raw, ham is always cooked” is an incomplete shortcut. The more dependable question is whether the particular product is sold ready to eat. [1] [2]
Suppose you need sandwiches for lunch now and a joint for a cooked meal at the weekend. A pack described as cooked sliced ham, ready to eat fits the first task. A joint described as uncooked gammon belongs with the second task and its cooking instructions. Their shared pork origin does not make them interchangeable at the point of serving. [1] [2]
If you buy gammon intending to use the cooked joint as ham, allow for the actual cooking and preparation steps. Do not lift a timing from a different joint just because the names match: the packet, joint and cooking method matter. The general distinction answers what you have bought; it does not calculate a cooking time. [3]

No. Gammon is available smoked or unsmoked and is ordinarily sold needing cooking. Smoking is not a replacement for checking readiness and instructions. [1]
No. That skips the required cooking stage. Choose a product explicitly ready to eat for a no-cooking sandwich use. [1] [2]
No. Ready-to-eat ham can be cooked or appropriately cured. Dry-cured hams are the exception that the simple “ham equals cooked” shortcut misses. [1] [2]
Gammon steak is an established dish name. The retail distinction concerns the uncooked product before preparation; it does not mean a cooked steak on a menu has been served raw. [1]
