What replaces it is a savory, faintly sweet flavor with a firm, chewy texture that crisps unusually well — which is why Pink Oyster is the species most often used for plant-based bacon. Slice it thin, press it in a hot dry pan until the edges crisp, then finish with fat and salt. It also holds up well in tacos, stir-fries, pasta, and soups.\u003c\/p\u003e\n\u003cp\u003ePlan to eat it fresh. Pink Oyster has the shortest shelf life of any gourmet mushroom, keeping only a couple of days in the fridge before it softens.
