Mushroom Stock

• 2kg Button mushrooms
• 6 Large field mushrooms, with the gills removed
• 50ml

Wipe the mushrooms clean with a damp cloth and finely slice them. In a large cast-iron pan heat the oil until smoking. Add the button and field mushrooms, garlic and shallots and sauté until golden brown. If the pan is not large enough, sauté the mushrooms in two batches as it is important that the pan maintains the heat otherwise the mushrooms will release their juice and end up boiling in it,
