Swiss Brown known also as Cremini or Roman Brown.
These golden brown mushrooms have a more robust flavour than the commonly cultivated white variety.
They remain firm when cooked and are a delicious addition to soups, stews and casseroles.
They may also be sauteed in garlic and butter and served with a sprinkling of lemon juice.
When they grow into mature flat mushrooms, they are called Portabella mushrooms.
