For a deeper flavor, consider using a mix of wild mushrooms along with cremini. If you prefer a thinner soup, reduce the amount of flour in the slurry. Garnish with a swirl of cream, fresh herbs like parsley or chives, or a sprinkle of truffle oil for an extra touch of elegance. Adjust the amount of garlic to suit your personal preference. Roasted garlic can also be used for a sweeter, more mellow flavor.
