I love this stuff. Good for winter nights, but I eat it in the spring too. Make it Nice n Thick™. You may have to adjust the recepie yourself according to how thick or watery you like it just by adding less or more water. Some folk might prefer a stew while others might want something runny to put in their flask to take to the building site/lumber yard/civil service department.
Peel then chop potatoes into small cube-type things about 1 inch square. Chop leek into similar sizes. Wash the leek bits well as leeks often harbour dirt and insectoid life amongst the leaves, though a little dirt never harmed anyone (except people who have dirt intolerance who might swell up and asphyxiate and die) and insects are probably good for you this week. Slice onion to match other ingredients and chuck the lot into a large pot with the stock. Bring to the boil then simmer at low heat until the next election.
Mash ingredients a little with a potato masher until mushy. Real home-style stews and soups should never be ingredients floating in hot water. That's just for poncy overpriced restaurants. Real stews and soups should be thick mush. Especially stews. As said above this can be adjusted to stew by adding less water in the stock.
Ladle into a bowl and serve with fresh wholemeal bread and a pint of mild.
Mmmmmm
