Any mushrooms; field, chestnut, button, portobello or a mix, work well here
4 large portions
Melt the butter in a large pan then sweat the onions and garlic for 5 minutes. Add 2/3 of the mushrooms and sweat for a further 5 minutes. Add the stock and simmer for 30 minutes. Add the remaining mushrooms, season and cook for 10 - 13 minutes.
Ladle this wonderful soup into bowls. A dash of chilli sherry makes this surprisingly special!
