The Crimini mushroom is one of the tastiest and is very versatile in its uses. When harvested young in the button stage it is called a crimini or baby bella and can be used in the same way as the regular white button mushroom. When harvested as a mature mushroom, with the gills exposed, it is called a Portabella. The crimini is probably 50% higher in solid content than the white button mushroom. This unique feature makes this mushroom meaty and wonderful. Crimini caps can grow as small as 1" across to as large as 2-3". Our mushroom kit grows several crops.
