5 minutes.

It usually takes about 5 minutes to cook. Soak the fungus in cold water for about 3-4 hours. Then prepare a pot, add an appropriate amount of water, and bring to a boil over high heat. After the water boils, add the soaked fungus. , wait until the water boils again, and continue cooking for about 5 minutes.

However, the blanching time varies depending on the quality of the fungus. The more resistant the fungus is to soaking, the better the quality. The faster the fungus soaks after being soaked in water, the worse the quality and taste will be. If the fungus of poor quality is to be mixed cold, soak it in water for 2-3 minutes and then pour it into cold water for mixing. The better-quality fungus is very resistant to cooking after soaking, and there will be no problem even if it is boiled for 10-15 minutes. If blanched for too long, the nutrients will be lost and the crispy texture will be lost.

How to choose fungus

1. In terms of shape, black fungus grows slowly in autumn, is thick, and has a lot of gum. Therefore, when choosing, check whether the shape of black fungus is uniform. If the flower shape is uniform and there are few curls, it means it is a high-quality black fungus. If there is less meat and more curls, try not to buy it.

2. In terms of color, the front and back of high-quality black fungus have different colors. Generally, the inside is black and shiny, and the back is gray with no obvious veins. If both sides are completely black, it is likely that chemicals have been sprayed by the merchant, so try not to buy it.

3. In terms of touch, most of the fungus we buy are dry. Therefore, when we choose, we first weigh them with our hands. The black fungus of the same size is lighter and of higher quality. There is a crisp sound when it is pressed, the surface is smooth, and it is particularly fragile. If the toughness is high and the sound is muffled when pinched, it means that the black fungus contains more water.

4. In terms of foaming rate, we don’t actually need to buy a lot when buying fungus, because high-quality black fungus has a high foaming rate, and buying too much may be a waste. When soaking, if you put high-quality black fungus in water, it will first float on the water surface, then slowly absorb water, expand, and slowly stretch out. The color will be brown and black, and finally float evenly in the water, with the edges of each piece They are all very thick, soft, smooth and elastic when eaten.
