There may be several reasons why the boletus turned purple after cooking. To understand what the color change is talking about and whether something can be done, you need to understand the features of these mushrooms.

Why butter boils turn purple when cooked

Every mushroom picker should know that this variety of mushrooms usually does not change color after heat treatment. In the process of boiling, it is not characterized by the appearance of blue, lilac, brown shades.

If the butter dish turns purple during cooking, this indicates the wrong cooking method. Legs and caps darken from too long heat treatment. With prolonged heating together with water, vegetable protein is destroyed, boiled mushroom raw materials have an unusual blue tint. Such a change may also depend on the growing area, when the composition of the soil and illumination can affect the peculiarity of the course of chemical reactions during heat treatment.

Pickled boletus turns purple when cooked due to the numerous additives in the form of spices, garlic, onion, and pepper. To avoid this, you need to boil the product several times, while the first water must be drained. It is recommended to add vinegar and a pinch of citric acid to the marinade.

Other mushrooms are the first reason why boletus darkens during heat treatment

The main reason for the sudden change in the color of mushrooms to dark or purple after boiling is the ingress of other species that look similar to boletus into the basket. Among the twins, goats (goats, or sieve) can be distinguished, which are easy to confuse when collecting. This is also an edible variety, which tastes almost the same as the "original".

Other forest plants also have the ability to change color, including:

  1. Mosswheel
  2. Grabovik

False oily oils turn black already at the cleaning stage. They differ from real representatives in a different structure of the cap: under it is not a sponge, but plates.

Violation of the cooking rules is the second reason why the boletus turned purple

The oiler is getting a purple hue due to improper processing technology. In order for the product to retain its original appearance after boiling, you need to cook, observing some simple rules:

  • large ripe fruits are peeled from the film;
  • the legs and caps are brought to a boil in clean water;
  • boil for no more than 5 - 10 minutes;
  • discard the mushroom mass in a colander;
  • Pour in salted water, after boiling, boil for 15 - 25 minutes, depending on the size of the fruit.

During the cooking process, a film may appear on the surface, which must be removed with a slotted spoon. The recommendation to change the water is due to the fact that, like reducers of oil, they absorb radiation and heavy metals, but they are destroyed during the first boil.

Is it worth worrying if the butter turns purple during cooking

Inexperienced mushroom pickers are alarmed by the fact that the collected prey changes its color to purple when cooking dishes. This can very well happen to edible specimens if boiled for more than a quarter of an hour. Do not worry if the selected product has all the varietal characteristics. Purple boletus obtained after cooking does not threaten human health and retain its usual taste.

What to do so that the butter does not turn black

It is especially unpleasant when the mushroom mass darkens in the jar after salting. The finished product does not look aesthetically pleasing, and the appearance of the dish does not evoke appetite. Experienced foresters advise adding a little citric acid and vinegar to the marinade. Sprinkle lemon juice on the dish before serving the roast. This will give a subtle sour taste and preserve the great appearance of the oil.

Advice! For harvesting for the winter, you should freeze the mushrooms, having previously boiled them for 10 - 15 minutes in acidified water.

How to cook butter so as not to darken

It is recommended to cook the product before any kind of further use:

  • before frying;
  • freezing;
  • slicing for salads;
  • for soup.

  1. Mushroom raw materials should be kept in boiling water for no more than 30 minutes.
  2. Reduce the boiling time to 15 minutes before frying.
  3. It is important to defrost the frozen workpiece beforehand, and then cook it in the same way as fresh mushrooms.
  4. Before freezing the butter, it is necessary to boil a little, dry it, put it in bags. It is permissible to harvest raw fruits.
