Step 1

Heat a large casserole pan and add 1 tbsp goose fat.

Step 2

Season 600g large chunks of shin beef and fry until golden brown, about 3-5 mins, then turn over and fry the other side until the meat is browned all over, adding more fat if necessary. Do this in 2-3 batches, transferring the meat to a colander set over a bowl when browned.

Step 3

In the same pan, fry 100g sliced smoked streaky bacon, 350g peeled shallots or pearl onions, 250g chestnut mushrooms, 2 sliced garlic cloves and 1 bouquet garni until lightly browned.

Step 4

Mix in 1 tbsp tomato purée and cook for a few mins, stirring the mixture. This enriches the bourguignon and makes a great base for the stew. Then return the beef and any drained juices to the pan and stir through.

Step 5

Pour over 750ml bottle red wine and about 100ml water so the meat bobs up from the liquid, but isn’t completely covered. Bring to the boil and use a spoon to scrape the caramelised cooking juices from the bottom of the pan – this will give the stew more flavour.

Step 6

Heat oven to 150C/fan 130C/gas Make a cartouche: tear off a square of foil slightly larger than the casserole, arrange it in the pan so it covers the top of the stew and trim away any excess foil. Cook for 3 hrs.

Step 7

If the sauce looks watery, remove the beef and veg with a slotted spoon, and set aside. Cook the sauce over a high heat for a few mins until the sauce has thickened a little, then return the beef and vegetables to the pan.

Step 8

To make the celeriac mash, peel 600g celeriac and cut into cubes. Heat 2 tbsp olive oil in a large frying pan. Tip in the celeriac and fry for 5 mins until it turns golden. Season well with salt and pepper.

Step 9

Stir in 1 or 2 sprigs of rosemary and thyme, 2 bay leaves and 4 cardamom pods, then pour over 200ml water, enough to nearly cover the celeriac. Turn the heat to low, partially cover the pan and leave to simmer for 25-30 mins.

Step 10

After 25-30 mins, the celeriac should be soft and most of the water will have evaporated. Drain away any remaining water, then remove the herb sprigs, bay and cardamom pods.

Step 11

Lightly crush with a potato masher, then finish with a glug of olive oil and season to taste.

Step 12

Spoon the beef bourguignon into serving bowls and place a large spoonful of the celeriac mash on top. Garnish with one of the bay leaves, if you like.
