BaÂ·sidÂ·iÂ·oÂ·myÂ·coÂ·ta. A phylum of fungi characterized by a spore-bearing organ, the basidium, that is usually a clavate cell that bears basidiospores after karyogamy and meiosis. Some mycologists have raised the class Basidiomycetes to the phylum or division level.
Add the onions to the skillet and increase the heat to medium-high. Cook until they begin to turn dark brown and somewhat soft, about 5 minutes. Add the oil and a pinch of the fine sea salt; continue cooking until the onions are soft and caramelized, about 5 minutes longer.. Soft, dark brown onions in five minutes. That is a lie. Fully caramelized onions in five minutes more.
1 Caramelize the onions: Check the onions every 5 to 10 minutes. Stir the onions and scrape up any fond that forms on the bottom of the skillet. â¢  Around 10 Minutes: Onions will start to soften and turn translucent in spots. They will release a lot of liquid into the pan.
