Cauliflower mushrooms are large and capless clusters of frilly, leaf-like branches joined at a thick base. They do resemble a head of cauliflower or even a coral reef! They're very delicate and brittle so be sure to handle carefully. With their musky-earthy aroma and mild, almond-like flavor, these mushrooms are the absolute best for frying in tempura or beer batter and serving pub-style.
