The conventional wisdom concerning the preparation of mushrooms varies greatly, owing much to the traditions and techniques handed down through generations. One popular belief, which my husband subscribes to, is that mushrooms should not be washed before cooking. This doctrine is rooted in the concern that mushrooms, being porous, can absorb water if exposed to it, potentially affecting their texture when cooked. This school of thought suggests that mushrooms should instead be wiped with a paper towel or a brush in order to remove any dirt.
This stance can be attributed to my husband's grandmother, who likely passed on her own culinary traditions based on her experiences and preferences. However, there is some debate over the matter. Many food safety experts and chefs offer varying notions about cleaning mushrooms, stressing the importance of removing any potential contaminants prior to consumption.
The Argument Against Washing Mushrooms
Here are a few reasons why some people, like my husband, prefer not to wash mushrooms:
1. Water Absorption: The primary argument against washing mushrooms is that they can absorb water, leading to a lessened flavor and a soggy texture once cooked.
2. Texture Preservation: Keeping mushrooms dry is said to preserve their texture, making it easier to achieve a crispy sear when sautéed or roasted.
