The chestnut mushrooms look like the button mushrooms, but they are colored in a darker nuance. The best chestnut mushrooms are the ones which are a bit curved and open and not flat, with a pink or brownish underside. The taste of the chestnut mushrooms is intense, strong and highly flavored and their texture is similar to meat – this is the reason why these kinds of mushrooms are great meat replacements. The chestnut mushrooms are available all year long and they can also be refrigerated for longer periods of time.
