The final touch to this delicious soup, apart from the truffle oil, is some hot toasty bread to go alongside. Don’t forget a good layer of butter. Ready in 30 minutes, this soup is a great mid-week dinner, or serve it as a starter to a fancy mid-winter dinner party.
- Melt the butter in a large pot. Add the leek and potato, then cover and cook slowly until the leeks have softened. Add the stock, thyme, salt and pepper, bringing to a simmer for 15 minutes. Remove and cool for 10 minutes before pureeing until smooth.
- Serve steaming hot with a sprinkle of toasted hazelnuts, a drizzle of truffle oil and buttered toast.
