Instructions
Roast the Chestnuts
Preheat oven to 220° C/425° FUsing a sharp knife cut an X into the shell of each chestnut, making sure to cut through to the inner skin of the chestnuts. This allows steam to escape and keeps them from exploding during cooking and makes peeling easier after roasting Place the chestnuts in a single layer on a baking sheet. Roast the chestnuts in the oven until the skin starts to peel away from chestnut, about 25 to 30 minutes. To check if they're ready, poke your knife through the opening where the skin has pulled back. It should easily pierce through. Remove the chestnuts from the oven and cover with a clean kitchen towel. Let rest until cool enough to handle, then peel the chestnuts using your hands, or a paring knife for any stubborn skins.
Prepare the Soup
In a large, heavy-bottom soup pot or Dutch oven, over medium heat, melt 15 grams (1 tbsp) of the butter; add the bacon and cook until starting to brown, but not crisp, about 5 minutes.
Add the shallots and celery root; cook until tender, about 10 minutes. Using a slotted spoon, transfer to a bowl, leaving the fat and butter in the pot.
Add the rest of the butter, mushrooms and chestnuts to the pot. Continue to cook on medium, stirring occasionally, until mushrooms have softened, about 5 minutes.
Add the shallot, celery root, bacon mixture back to the pot along with 60 ml (¼ cup of the stock, stir to combine.
Add the Port and cook until the alcohol has burned off, 1-2 minutes
Add the rest of the stock along with the sage, thyme and bay leaf to the pot. Bring to a gentle boil, reduce the heat to medium-low and simmer for about 30 minutes, stirring often.
Remove the herbs; discard.
Working in batches, transfer the soup to a blender and purée soup until smooth. return to the pot, taste, and adjust for salt and pepper.
When ready to serve, heat the soup to a simmer. Remove from the heat and add the cream, stirring to combine.
Serve garnished with a swirl of cream and a sprig of thyme.
