How to Keep Mushrooms White
- 1). Keep the mushrooms whole until you are ready to use them. If you slice them too far in advance, exposed surfaces may turn brown.
- 2). Dip the white mushrooms in a bowl of lemon juice just before using them. The acid in the lemon juice helps to prevent the air from reacting with the mushroom's surface. This technique will preserve the mushrooms' color after slicing as well as during the cooking or canning process.
- 3). Remove the mushrooms quickly, and dry them well with a soft towel so that they do not get soggy. A few minutes in the solution is usually sufficient.
- 4). Store uncooked white mushrooms in the refrigerator. They will turn brown quickly if left at room temperature.
- 5). Wrap mushrooms that you don't plan to use for awhile in a damp cloth, or store them loosely in a paper bag in the fridge. These techniques limit mushrooms' exposure to air, while keeping them fresher than they would be if stored in an air-tight container.
