Mary Berry Split Pea and Gammon Soup Recipe Ingredients
- 500 g (1 lb) green split peas
- 500 g (1 lb) gammon knuckle
- 2.5 litres (4 pints) water
- 1 large onion, finely chopped
- 4 celery stalks, finely chopped
- 200 g (7 oz) potatoes, peeled and diced
- 3 leeks, trimmed and sliced
- Salt and freshly ground black pepper
- 2 tablespoons fresh parsley, chopped (for garnish)

How To Make Mary Berry Split Pea and Gammon Soup Recipe
- The overnight soak: This initial step is essential for both the texture of the peas and the salt level of the meat. Put the green split peas and the gammon knuckle into separate large bowls and cover them generously with cold water. Leave them to soak overnight. This softens the peas for even cooking and draws out excess salt from the gammon.
- The initial simmer: The next day, drain the split peas and the gammon knuckle thoroughly. Place them both into a large, heavy-based saucepan or a stockpot and add the 2.5 litres of fresh water. Bring the mixture to a boil over high heat, then reduce to a simmer. Leave it to cook, uncovered, for about 1 hour.
- The slow cook: Stir in the finely chopped onion, celery, diced potatoes, and sliced leeks. Cover the pan with a tight-fitting lid and simmer very gently for a further 2.5 hours. During this long, slow cook, the gammon will become meltingly tender and the split peas will break down into a thick, creamy broth. If the soup looks too thick at any point, feel free to add a little more water.
- Shred the gammon: Use a slotted spoon to remove the gammon knuckle from the saucepan and set it aside to cool slightly. Carefully pull the meat away from the knuckle bone using two forks. Discard the bone, skin, and any excess fat. Coarsely chop the succulent ham meat into bite-sized pieces.
- Finish and season: Return the chopped ham to the saucepan. Stir well and season with salt and plenty of black pepper to your taste—be cautious with the salt, as the gammon may have provided enough already. Heat gently for a few minutes to ensure the meat is warmed through. Serve hot, garnished with a generous sprinkling of fresh parsley.

Recipe Tips
- Gammon Knuckle: As Mary suggests in her “Cook’s know-how,” gammon knuckles are meaty yet very inexpensive. They provide a depth of flavor that diced ham simply cannot match. If you can’t find them in the supermarket, your local butcher will certainly have them.
- Pea Texture: If you prefer a smoother soup, you can remove the meat and pulse the vegetable and pea base with an immersion blender before adding the chopped ham back in.
- The “Salt” Check: Always taste the soup after adding the meat back in before adding extra salt. Gammon varies in saltiness, and you may find the broth is already perfectly seasoned.
- Consistency: This soup is notoriously thick (sometimes called “London Particular”). If it sits for a while, it will thicken even further; simply stir in a splash of boiling water to loosen it before serving.

FAQs
Do I have to soak the peas?
While u0022no-soaku0022 split peas exist, Mary’s traditional method ensures the peas are perfectly tender and have a better consistency. Soaking the gammon is also vital to prevent the soup from being overly salty.
Can I use a slow cooker?
Yes. After the initial 1-hour boil on the stove (which is important for food safety with gammon), transfer everything to a slow cooker and cook on Low for 7-8 hours.
What if I can’t find a gammon knuckle?
You can use a gammon joint or even thick-cut smoked bacon, though the flavor won’t be quite as rich as it would be using the bone-in knuckle.
