How to clean and cook birch boletes

The scaber stalk (brown birch bolete) is a generous, tasty mushroom, but it has two quirks you'll need to get used to: it darkens quickly and easily goes mushy. Once you know a few simple tricks, these traits stop getting in the way.

Let's follow the birch bolete's whole journey through the kitchen: how to clean it, whether to boil it first, how to fry, pickle and dry it. And we'll start with the most important rule: don't put it off.

Don't wait after your forest trip

The birch bolete spoils faster than many other mushrooms. Its tender flesh goes mushy, darkens and attracts maggots within a day.

So the main rule is this: get to work on your mushrooms as soon as you're back from the forest. The fresher the birch bolete, the easier it is to clean and the tastier it will be on the table.

If you can't do it right away, keep the mushrooms in the fridge, but for no longer than a day. Birch boletes that sit too long lose their firmness and flavor.

How to clean birch boletes

Cleaning birch boletes is easy, and there's no need to peel them.

Trim off the lower, dirty part of the stem.
Use a knife or brush to clean off stuck-on needles, leaves and sand.
Cut each mushroom open and check for maggots; trim away the affected spots.
Rinse quickly in cold water, but don't soak them for long: birch boletes absorb water and go mushy.

It's best not to pick old mushrooms with a soft, dark sponge at all, and if you did, cut away their spongy layer. Young, firm birch boletes are the easiest to clean.

Do you need to boil birch boletes first?

It all depends on the dish.

For frying, you don't have to boil birch boletes, just clean them well. But many cooks still boil them for 10–15 minutes and drain the water so the mushrooms are cleaner and darken less in the finished dish.

For pickling and freezing, boiling is pretty much a must: it makes the mushrooms safer to store and helps them hold their shape. So the rule is simple: you can fry them without boiling, but for preserving it's better to boil them first.

How to fry birch boletes

Fried birch boletes with potatoes or onions are a classic of Ukrainian cooking.

Clean the mushrooms and cut them into pieces.
If you like, boil them for 10–15 minutes and drain in a colander.
Put them in a dry pan and let the excess moisture evaporate.
Add oil or butter and onion, and fry until done, 15–20 minutes.
Salt at the end; sour cream or fresh herbs make a nice addition.

Don't be alarmed when the mushrooms darken, almost to black. It's a natural property of the birch bolete and has no effect on taste or safety.

How to pickle and dry birch boletes

For winter preserves, firmer birch boletes, such as Leccinum melaneum, work best.

Pickling. Boil the cleaned birch boletes for 15–20 minutes, drain, then simmer them in the marinade (per liter of water: a spoonful of salt, one and a half spoonfuls of sugar, 50–70 ml of 9% vinegar, spices) for another 10 minutes and pack into sterilized jars. Use young, firm mushrooms of the same size.

Drying. Don't wash the mushrooms before drying, just clean them dry. Slice them and dry in a dehydrator or oven at 45–50 °C. Properly dried mushrooms should snap, not bend. Dried birch boletes are dark, but they add wonderful aroma to soups and sauces.

A few general tips

Let's sum up what will make your birch bolete dishes tastier.

Pick young mushrooms: old ones go mushy and spoil the texture of the dish.
Don't soak birch boletes for long, they soak up water like a sponge.
Cook them right after your forest trip, without putting it off.
Combine birch boletes with red-capped scaber stalks and other mushrooms: together they're tasty and look great.

And of course, it all starts with a good forage. To avoid coming home from the forest empty-handed, let the weather guide you with our mushroom radar: it shows when moisture and warmth line up well for mushrooms to appear in deciduous and mixed forests.
