This recipe is made by slowly cooking mushrooms with onions and garlic until deeply flavorful, simmering them with stock, then blending the mixture into a smooth soup and finishing with cream. Cooking the mushrooms properly at the start is key, as it draws out their moisture and concentrates their natural umami. The final result is a velvety soup with a clean, balanced mushroom taste.
