The Portobellini is closely related to the white mushroom (we think they are cousins) as they are similar in size and shape. The difference is its brown exterior colour and its nutty, earthy, more intense flavour.
Around the world they are also known as Chestnut mushrooms, Cremini and Baby Bella.
When the Portobellini mushrooms are allowed to grow further in size developing a darker skin and an opened-cap exposing the gills on the underside they are then called Portobello.
Portobellinis make a great substitute for white mushrooms so why not go ahead and try them the next time you would like to add some zing to your food?
