Method
- Melt the butter in a large pot over medium heat. Add the onion, celery, and carrot. Sweat the veggies until softened, about 10 minutes, stirring frequently.
- Add the garlic to the pot and cook it for about 1 minute, until very fragrant.
- Begin sprinkling the flour into the pot, a bit at a time, stirring between additions so the flour coats the veggies. Cook the veggies and flour for about a minute, stirring frequently.
- Begin adding broth to the pot, a bit at a time, whisking each addition in to eliminate any lumps formed by the flour.
- Once all the broth has been added, stir in the milk, potatoes, bay leaf and thyme. Raise the heat and bring the liquid to a boil.
- Lower the heat and allow the soup to simmer, stirring occasionally, until the base thickens a bit and the potatoes are tender, about 25 to 30 minutes.
- Remove the pot from heat. Remove and discard the bay leaves. Stir in the vinegar and season the soup with salt and pepper to taste. Ladle into bowls and serve.
