Buying and Storing Mushrooms for Optimal Freshness
Look for mushrooms that are firm, dry (not slimy), and free from bruising or discoloration. To store, keep them unwashed in a paper bag in the refrigerator, which helps prevent moisture accumulation and mildew. Use within one week for best taste and texture. Avoid storing mushrooms in airtight containers, as this can trap humidity and accelerate spoilage.
Things to Consider When Eating Mushrooms
While mushrooms are safe and nutritious for most people, here are a few points to remember:
- Some individuals may have allergies or sensitivities to certain mushroom species. If new to mushrooms, start with small amounts.
- Raw mushrooms contain small amounts of compounds like agaritine, which are mostly broken down by cooking. Cooking mushrooms is recommended for better digestibility and safety.
- If you are foraging, never consume wild mushrooms unless identified as safe by an expert – some wild varieties are highly toxic.
