How to dry butter in the oven

Drying butter in the oven of a gas stove is an easy and quick way, even in a city apartment. The process will take no more than 5 hours, and it is performed in the following sequence:

  1. Prepare baking sheets by covering them with foil or baking paper.
  2. Peeled and chopped butter is laid out on a baking sheet in one layer, placed in the oven.
  3. At a temperature of no more than 50 degrees, they are kept in the oven for 1.5 - 2 hours, slightly withering.
  4. The temperature is increased to 70 degrees and the butter oil continues to dry for another 30 - 60 minutes.
  5. Dried, lowering the temperature to 50 degrees.
  6. Readiness is checked by breaking a mushroom wedge.
Advice! To prevent moisture condensation on dried mushrooms, do not close the oven door tightly during drying, allowing air to circulate. Mushrooms, for uniform drying, periodically turn over and rearrange the baking sheets.

Drying oil in an electric oven

Modern electric ovens can operate in convection mode, providing forced ventilation and creating optimal conditions for drying. If there is no such function, then the oven door is also kept ajar to evaporate the liquid.

Advice! If the butter is placed not on baking trays, but on grates or strung on skewers, then there is no need to turn them over when drying.

In an electric oven, butter oil can be dried according to the following scheme:

  1. In convection mode - at a temperature of 40-50 degrees, they are dried for about 3 hours to remove most of the moisture.
  2. Raising the temperature to 70 degrees, they are kept for another 1 - 1.5 hours.
  3. Dried until tender, lowering the temperature to 45 - 50 degrees.
Important! When drying in an electric or gas oven, the temperature is adjusted smoothly, avoiding sudden jumps. Its increase over 70 degrees leads to the brewing of proteins and darkening of the mushrooms.

How to dry boletus at home in the oven

At home, oil can be dried in an oven. They are split into a sieve, plywood sheets or baking trays lined with straw and placed in a cooling oven. If the moisture starts to foam, it means that the oven temperature is too high. In this case, remove the baking sheets and wait for the oven to cool. The optimum temperature for drying is 60 degrees: at a higher temperature, the mushrooms will burn, at a lower temperature, they will sour.

Such drying is a cyclical process. The mushrooms are placed in the oven each time before finishing the firebox. They will dry out in at least 4 days, depending on the frequency of kindling.

  4. After the timer signal and the microwave oven is turned off, open its door and ventilate it from moisture for 5 to 10 minutes.
  5. Items 3 and 4 are repeated three to five times until the liquid has completely evaporated.
  6. Readiness is checked by breaking a slice.

The main advantage of this method for drying mushrooms is a short drying time, about 1.5 hours. However, this method is energy-consuming and not suitable for large crop lots.

How to properly dry boletus in an airfryer

Conveyor grill is a modern universal device in which butter oil can be dried. For this:

  • cover the grill with baking paper so that small pieces do not spill out;
  • butter oil is laid out on a lattice in one layer;
  • the grate is placed in the airfryer;
  • on the dashboard, set the blowing speed to the maximum value, and the temperature to 70 - 75 degrees;
  • the lid is left slightly open so that the humid air comes out of the airfryer, and the food is dried, not boiled.

Drying time in the airfryer is about 2 - 2.5 hours.

How to dry butter in an electric dryer

Oils can also be dried in an electric dryer. The principle of its operation is based on the supply of heated air to special pallets. Convective dryers evaporate moisture by circulating the air flow. Infrared units use radiation to influence the water molecule in the product structure.

Drying oil in an electric dryer consists of the following stages:

  1. Peeled and chopped mushrooms are laid out tightly in one layer on pallets.
  2. The pallets are placed in the dryer.
  3. Turn on the "Mushrooms" function on the electric dryer. If it is not provided, set the temperature to 60 degrees.
  4. The pallets are periodically swapped.
  5. At the end of the process, the dried mushrooms are removed from the trays.

Drying time in an electric dryer depends on the thickness of the slices and the humidity in the room. On average, it takes 12 to 20 hours.

Drying butter in the sun

Drying butter oil in the open air is possible only in hot sunny weather. After preparing them:

  • laid out on sieves, baking sheets or plywood sheets and exposed in a sunny place;
  • placed on a gauze folded in several layers, stretched horizontally on a wooden frame.

Important! Do not allow moisture to come into contact with dried oil. It is good to cover them with gauze in one layer - to protect them from insects and dust.

At night, pallets or garlands are brought into the room so that the mushrooms do not begin to absorb moisture. Drying time depends on weather and placement. On hot sunny days, boletus, suspended on threads, dry out in 12 - 30 hours, and if they are on pallets, it will take up to 4 days.
