How to clean mushrooms

Can you wash mushrooms? Myth vs reality

Yes: a quick rinse is fine, as long as you dry them straight away and never leave them soaking. You may have heard that mushrooms should never be washed, but the truth is more relaxed: mushrooms don’t soak up water like a sponge, but a wet surface steams in the pan instead of browning, and the texture goes soft. The real problem isn’t water, it’s how long they sit in it.

For most mushrooms a quick rinse followed by an immediate pat-dry is perfectly fine. The Mushroom Council also suggests brushing them off or rinsing briefly under running water and patting dry.

• Don’t leave mushrooms in a bowl of water; hold them under the tap for a few seconds only.
• Pat them dry straight away with a clean tea towel or kitchen paper.
• Clean right before cooking, not before storing.

Button, oyster, shiitake and lion’s mane

Store-bought mushrooms are usually grown clean, so a brush or damp cloth is often all you need. If there’s a lot of growing medium on them, a short rinse is fine.

• Button and cremini: Wipe the caps with damp kitchen paper and trim a thin slice off the dried stem end. Rinse briefly only if they are very dirty, then dry.
• Oyster mushrooms: Hold the cluster from below, cut off the shared base and pull the mushrooms apart. They rarely need washing; shake or brush off any bits.
• Shiitake: Wipe the caps. The stems are tough, so cut or twist them off. Don’t toss them; save them in a container for stock or broth.
• Lion’s mane: Its spongy texture holds water easily, so skip the rinse. Trim any darkened or tough base and brush away loose bits.

Morels (kuzugöbeği): hollow, so slice them in half

The honeycombed cap and hollow body of morels — kuzugöbeği in Turkish — easily hide sand, grit and tiny insects. With morels the goal isn’t to avoid washing but to wash them well.

1. Trim the dirty stem end.
2. Slice each morel in half lengthways; it should be completely hollow. If it has a cottony filling or turns out solid inside, don’t use it and ask an expert.
3. Check inside for sand and insects and clean with a soft brush.
4. Rinse quickly under cold running water; if very sandy, dunk briefly in cold water and lift out — don’t let them soak.
5. Drain in a colander, dry well on kitchen paper and cook right away.

Saffron milk caps (kanlıca) and other wild mushrooms

Wild mushrooms like saffron milk caps (kanlıca) come out of the forest with soil, pine needles and sometimes larvae. Pick off leaves and needles by hand first, then brush. Trim the dirty stem base, cut through cap and stem to check for worm tunnels, and discard heavily infested parts.

Only use wild mushrooms that have been identified by an expert or bought from a trusted seller. Cleaning is not identification — if you’re not sure what it is, keep it out of the kitchen.

• Saffron milk caps bleed an orange juice when cut. That’s normal, but never rely on it alone to identify a mushroom.
• Throw away any parts that are mushy, smelly or slimy; spoiled mushrooms should not be eaten.
• If you suspect poisoning, act immediately: call your local emergency number (112 in Türkiye) or a poison control centre (114, the National Poison Information Center, in Türkiye).

When not to wash mushrooms

• When you aren’t cooking them right away: wet mushrooms turn slimy and spoil quickly in the fridge.
• When slicing them thin for a raw salad and they’re already clean: a wipe with a damp towel is enough.
• When you plan to dry them: water slows drying, so brushing works better.
• With water-hungry mushrooms like lion’s mane and oyster: brushing and wiping usually do the job.
