Cultivated vs Wild Mushrooms in Australia
Cultivated mushrooms (button, cremini, portobello, shiitake, oyster) are grown in controlled environments and are available year-round. Quality fluctuates little with season — focus entirely on freshness at purchase.
Wild mushrooms are strictly seasonal. Australia's most prized wild mushroom is the saffron milk cap (pine mushroom), which appears under pine trees in Victoria and South Australia from March to June after rain. Other foraged varieties include slippery jacks and porcini in cooler regions.
How to Pick Fresh Mushrooms
- Cap surface: Smooth, dry, and firm. Slimy or wet caps mean they're deteriorating fast.
- Gills (underside): For open-cap varieties, gills should be pink (button mushrooms) or a consistent colour with no dark patches.
- Stem: Firm, not hollow or shrivelled. A dry, intact stem is a sign of freshness.
- Smell: Earthy and clean. Any sour, ammonia, or fermented smell means they've turned.
- Colour: White mushrooms should be uniformly white or cream — not spotted or browning.
Never Wash Mushrooms in Water
Mushrooms are like sponges — they absorb water quickly, which makes them steam rather than sear when cooked (resulting in rubbery, pale mushrooms). Instead, wipe with a damp paper towel just before cooking. For very dirty mushrooms, a quick rinse followed by immediate thorough drying is acceptable.
Storage
Store mushrooms in a paper bag in the fridge — paper absorbs moisture while allowing airflow. Never store in plastic, which traps humidity and accelerates sliminess. Use within 5–7 days. Cooked mushrooms keep for 3 days refrigerated.
