Chef's TipsMushrooms are around 90% water — overcrowd the pan, and they steam instead of sear, releasing water and turning grey and rubbery instead of browning. Give them space and don't touch them too soon, and you get the actual restaurant-style sear.
Storage & ReheatingStore in an airtight container in the fridge for up to 3 days. Reheat in a hot pan for 2–3 minutes — reheating from cold in a pan brings back texture better than a microwave.
