Pleurotus ostreatus, letinous edodes, flammulina velutipes...... There are many kinds of mushrooms in the market. How can we pick fresh ones? Let me introduce you here.
Pleurotus ostreatus is to choose small cap. The choice of Pleurotus ostreatus should pay attention to the morphology of the cap, and the margin of the fresh pleurotus ostreatus is slightly curled down without cracking. If the edge has been flat and cracked, it is too old to taste. In addition, we should also pay attention to the size of the pleurotus ostreatus’ cap when selecting. The big size of the cap is not good. The smaller one is more fresh, tender and tasty, and the diameter of cap about 5 cm is the best.
The choice of Pleurotus eryngii is to choose length with 12~15 cm. Fresh pleurotus eryngii has the following characteristics: first, its surface is shiny, milky white and feels smooth; second, its pleats are arranged closely, its edges and sides are smooth; third, its body is compact and its length is 12-15 cm. The dried Pleurotus eryngii mushroom is too old to touch, and over 15 centimeters belong to overgrowth. The fungus is often empty and not tender enough.
Flammulina velutipes is covered with hemispheres. Flammulina velutipes stalks are generally shallow and deep, if the color is uniform and bright, it is likely to be treated by bleaching or dealing with additives. The cap choice of flammulina velutipes should be hemispherical. The open cap of flammulina velutipes is old, and the stalk of flammulina velutipes with the length of 15 cm is best. In addition, pay attention to the color, white flammulina velutipes is tough, easy to plug teeth, and yellow flammulina velutipes is fragrance, tender taste, more delicious.
Letinous edodes should be rich in aroma. Letinous edodes is famous for its special aroma. Therefore, it is the first choice to choose a strong aroma. Fresh letinous edodes cap of good quality is thicker and slightly curled down, its pleats tend to be white and dry. The pleats are the freshest and the diameter of the cap is 3~6 cm. The stalk is short and tender. If there are brown spots on the pleat, the surface of the cap is deep colour , slippery or dripping, it is unfit to eat.
We choose straw mushrooms to pick color with a clear distinction between black and white. Straw mushrooms with smaller size and with a clear distinction between black and white are usually tender. Press the surface with your hands. If it feels soft or water, it means that it is not fresh or even deteriorated.
Tricholoma should not be more than 4 cm in diameter. Tricholoma is white with gray. If the color is too white, it may be bleached. The size of the mushroom determines the maturity of the mushroom. Generally, it is better to choose a small one. The diameter of the mushroom should not exceed 4 cm. The cap tightly encloses the stalk as the top grade. If the cap and the stalk are separated and see the hyphae inside, don't buy it. It should be reminded that mushrooms should not be preserved and should be cooked immediately after purchase.
