Cleaning Slippery Jack mushrooms (Butterpilze) is a bit more of a project than your average mushroom prep, mostly because you’ve got to deal with that signature slimy cap. The cleaning process actually starts right there on the forest floor and follows you back into the kitchen. One fair warning, though: if you don’t protect your hands, you’ll be wearing “mushroom tan” stains for days!
How to “Harvest” Slippery Jacks the Right Way
Only the best, cleanest mushrooms should make it into your frying pan. That means the sorting and pre-cleaning starts the moment you find them. When you head out, bring a basket, a cloth, and a sharp knife. Once you spot a Slippery Jack, cut it about half an inch above the ground and use your cloth to wipe the sticky film off the cap. Then, slice the mushroom in half lengthwise to check for uninvited guests—these mushrooms are notorious for being full of maggots.
Pro Tip:
Wear disposable gloves while foraging and cleaning. Direct contact with these mushrooms causes stubborn skin discoloration that’s a real pain to scrub off.
Clean Your Haul Immediately
I know, a long foraging hike can be exhausting, but don’t let your mushrooms sit! You should clean your Slippery Jacks as soon as you get home. These little guys are best enjoyed when they’re fresh.
- Trim away any bite marks from critters or damaged spots.
- Peel the skin off the cap. This is a must, as the skin can cause digestive upset for some people.
- Give them a thorough cleaning. A dedicated mushroom brush is your best friend here.
- Place the cleaned mushrooms in a colander and give them a very quick rinse with water.
- Make sure to cook them thoroughly for at least 15 minutes.
Start with Small Portions
The Slippery Jack (scientifically known as *Suillus luteus*) is a popular choice for the table. It’s edible and non-toxic, but it can be a bit tricky for sensitive stomachs. Some people experience gastrointestinal issues or mild allergic reactions, often depending on how much they eat. If you’ve never tried them before, start with a small portion to see how your body handles them.
Pro Tip:
Fresh mushrooms don’t stay fresh for long, but don’t feel like you have to eat a massive haul all at once. Slippery Jacks are incredibly easy to dry, and they keep their wonderful, aromatic flavor perfectly.
