How to buy fresh portobello mushrooms:

1. Look at the maturity

Don't buy especially ripe portobello mushrooms, mushrooms that are too ripe are often on the verge of rotting and spoilage, and their flesh is flabby and not good to eat, so it's better to buy the ones that are ripe.

2. Look at the color

Good portobello mushrooms appear naturally dry and white, if the color is too dirty, they may be old, sprayed with water or contaminated with dirt.

3. Observe the appearance

At a glance, most of the mushrooms that do not have rotten mouths or water stains on the surface and are not sticky to the touch are good mushrooms.
