Scottish Lentil Soup with Ham Hough

Scottish Lentil Soup with Ham Hough

Created by Chef Thomas

A one-pot soup where red lentils dissolve into a smoky ham broth without any help, thickening themselves into something that feels like it took all day but asked very little of you.

January rain on the window. The heating on. A smoked ham hough in the pan, doing its quiet, patient work of turning water into stock. This is the soup for that evening.

Scottish lentil soup is not a recipe so much as a principle: put a ham bone in water, add red lentils and whatever root vegetables are in the house, and wait. The lentils do the rest. They dissolve entirely, falling apart into the broth until the whole pot turns thick and velvety without anyone having to reach for a blender. The ham hough gives the salty, smoky backbone that holds everything together. It costs almost nothing and feeds a household for two days.

I first had this in a farmhouse kitchen in Perthshire, years ago now, stood at the range with a bowl in both hands because it was too cold to sit still. It tasted of smoke and warmth and someone paying attention. I wrote it down in the notebook that night: lentils, ham, turnip, rain. That was enough to bring it back every winter since.

A recipe is a conversation, not a contract. The vegetables are suggestions. Use what you have, what looked decent at the market, what needs using up. A parsnip instead of the turnip. A leek instead of the onion. The lentils and the hough are the constants. Everything else follows your kitchen, your evening, your appetite.

The technique, the tradition, and the story behind every dish.

Instructions

  1. 1

    Start the hough

    Put the ham hough in your largest pan and cover it with the cold water. Bring it to a gentle simmer. A scum will rise to the surface in the first few minutes. Skim it off with a spoon and don't worry about it. This is just the protein doing what protein does. Once the broth is running clear, add the bay leaves and thyme, put a lid on slightly ajar, and let it tick away for forty-five minutes to an hour. The kitchen will start to smell of something good and salty and smoky. That's your stock building itself.

    Ask your butcher for a smoked hough, not a green one. The smoke is the whole backbone of this soup. A good butcher will have them, and they cost next to nothing for what they give you.
  2. 2

    Add the vegetables and lentils

    Lift the hough out onto a board and set it aside. Don't throw away the broth. That broth is the point. Add the onions, carrots, celery, turnip, and potatoes to the pot. Give it a stir, then tip in the rinsed lentils. Bring it back to a steady simmer. The lentils will start to break down almost immediately, which is exactly what you want. They'll thicken the soup from within, no blending needed.

  3. 3

    Shred the ham

    While the soup simmers, deal with the hough. The meat should be soft enough to pull away from the bone with two forks. Shred it into rough pieces, discarding the skin, fat, and bone. Don't be too tidy about it. Some pieces bigger, some smaller. The bone and any trimmings can go back into the pot for the last twenty minutes if you like, then fished out before serving. Every bit of flavour counts.

    The hough gives more than meat. The bone, the connective tissue, the marrow: they all dissolve into the broth over time and give the soup a body that no amount of lentils alone can match.
  4. 4

    Simmer until thick

    Cook the soup for another thirty to forty minutes, stirring now and then to stop the lentils catching on the bottom. They stick when they thicken, and they thicken without warning. The soup is ready when the lentils have dissolved into the broth entirely and the carrots and turnip are soft but not collapsing. It should be thick, properly thick, the sort of soup that holds a wooden spoon upright for a second before it topples. If it's too thick, add a splash of water. If it's too thin, give it longer.

  5. 5

    Finish and serve

    Stir the shredded ham back through the soup. Taste it. The hough will have given the broth plenty of salt, so check before you add any more. A good grind of black pepper. Fish out the bay leaves and thyme stalks. Ladle it into warm bowls, generous portions, and put bread on the table. The kind of bread that can take a bit of dunking.

Chef Tips

  • The soup improves overnight. Something happens as it sits in the fridge: the flavours settle into each other and the texture thickens further. Reheat it gently the next day with a splash of water to loosen it, and it will be better than the first serving. This is a soup that rewards patience and leftovers in equal measure.
  • Don't salt the water at the start. The ham hough carries its own salt, and you won't know how much until it has simmered for an hour. Taste at the end and adjust then. You can always add salt. You can't take it back.
  • If you can't find a smoked hough, a piece of smoked bacon or a ham bone will do. The smoke is what matters. Without it, the soup is pleasant but not itself. Ask the butcher. They usually have houghs tucked away somewhere, and they're the cheapest cut in the shop.
  • Stir the pot every now and then once the lentils go in. Red lentils are well-meaning but careless: they'll stick to the bottom and catch if you forget about them. A wooden spoon, a scrape across the base, every ten minutes or so. That's all it takes.

Advance Preparation

  • The whole soup can be made a day or two ahead and kept refrigerated. It thickens considerably as it cools, so add a splash of water when reheating and stir well over a gentle heat.
  • The ham hough can be simmered and the stock made the day before. Refrigerate the stock overnight, shred the meat, and finish the soup with the vegetables and lentils the next day. This splits the work neatly across two evenings.
  • Freezes well for up to three months. Defrost overnight in the fridge and reheat gently, adding water to bring it back to the right consistency.
