When there's a chill in the air, there's nothing better than a big steaming pot of sausage and lentils - with lots of lovely veg in there too. Every version of this I make is a little different depending on what's in the garden or the larder. The apple and sage finish is a brilliant addition from Kity Coles, who helped test many of the recipes in this book.
Based on 6 servings, adjust as needed.
Heat a little oil or fat in a large flameproof casserole over a medium heat. Add the sausages and cook for 5-7 minutes, turning, until browned. Remove with a slotted spoon and set aside on a plate.
Toss the fennel or caraway seeds, if using, into the pan and fry for a minute or so, then add the onions, carrots, celery, and celeriac. Cook for 10-12 minutes until the vegetables are starting to soften, stirring often and scraping up any brown bits from the sausages. Add the garlic and cook for another couple of minutes.
Now add the paprika, lentils, rosemary, thyme, mustard and a few twists of pepper. Spoon in the tomato purée and stir well. Cut each sausage into 3 or 4 pieces and add back to the casserole. Pour on the stock, then add enough water just to cover everything. Stir well and bring to a simmer.
Lower the heat and simmer very gently, uncovered, for 25 minutes or so, stirring occasionally, until the veg and lentils are tender. Stir in the kale or cavolo and simmer for a further 5 minutes.
Meanwhile, prepare the apple and sage topping if you fancy it. Quarter and core the apple(s) and cut into 3cm chunks. Heat a little oil or fat in a small frying pan over a medium-high heat, then add the apple(s). Fry for 3 minutes until glazed, tossing and stirring occasionally, and seasoning with a pinch of salt and a twist of pepper halfway through. Tip into a warmed bowl.
Add a dash more oil to the pan, toss in the sage leaves and fry for 1-2 minutes to crisp up.
Taste the casserole for seasoning, adding more if needed. Ladle into warmed plates or bowls and top each portion with a spoonful of apples and a few crispy sage leaves, if serving.
