Cremini mushrooms, similar in size and shape to common cultivated white mushrooms, have a more pronounced flavor and a rich brown skin concealing creamy tan flesh. Select firm, plump mushrooms that are not slimy or bruised. Store mushrooms unwashed-lightly wrapped in paper towels or in a paper bag, never in plastic-in the refrigerator.
To clean cremini mushrooms:
Remove grit from the mushrooms by wiping with a damp paper towel or mushroom brush. For a more thorough cleaning, swish the mushrooms very briefly in water, then pat dry with paper towels.For other mushroom varieties, see button, chanterelle, Chinese black, cultivated, oyster, porcini, portobello, shiitake, straw, and tree ear mushrooms, and truffles.
