Portobello also called Portabella is simply a brown crimini mushroom in disguise. Evidently the usage of these two terms is simply an issue of size. Once the little brown crimini grows to 4″ – 6″ in diameter, it is deemed to be a portobello. Portobello in Northern Italy is called “cappellone” which means “big hat”. The origin of the name is unsure as there are as many “origins” as there are experts to quote them. The most important thing to know is that it is essentially the big brother of the little brown mushroom.
