For me one of the best things about winter is homemade soup. In the old days Mum’s soups started with ham, chicken, lamb or whatever bones she bought at the butcher’s that week. She’d add vegetables and then cover the lot with cold water, bring it to the boil and cook it for a few hours. The next step was to allow the soup to cool so that the fat from the bones could solidify and it was then carefully taken off. The resulting soup was worth all that effort, but modern recipes like this one make the job a whole lot easier.
