While most mushrooms are available year-round, many are at their peak in fall and winter.
To select, look for firm, evenly colored mushrooms. Avoid mushrooms that are broken, damaged, or have soft spots, as well as those that seem damp or smell of mildew. It's a good idea to hand-select mushrooms; choose those of equal size if they are to be cooked whole, so they'll cook evenly.
