Forestière literally translates to foresty, or in the manner of the forest. It relates to wild mushrooms that you would find in the forest, typically made into a sauce, a side dish or a garnish. It can also be used to describe a mushroom pâté, or pâté forestière, where the wild mushrooms run through it. Many people still do this in France, gathering mushrooms in wicker baskets to use in cooking at home. Obviously, most of us can't tell the difference between a posonous mushroom and an edible one. However, many pharmacies will happily check anything you have picked, to make sure that they are safe to eat. Luckily, many retailers now stock different varieties of mushrooms with different flavours that a re perfectly safe to eat!
