Sachet d’épices (spice sachet) and bouquet garni (bundle of herbs) are bundles of spices and/or herbs that are used to add flavor to a simmering broth, soup, or stew. A basic sachet or bouquet will flavor 2½ to 3 quarts of liquid.
Sachet d’Épices
To make a sachet, cut a small square of cheesecloth and a short length of kitchen twine. Place 5 to 6 peppercorns, 3 to 4 parsley stems, 1 sprig thyme (or ½ teaspoon dried thyme), and 1 bay leaf in the center. If desired, a garlic clove can be added. Bring the corners of the cheesecloth up to the center and twist them to form a bundle. Tie the top of the sachet with the twine to secure. If desired, the twine can be left long and tied to the pot handle during cooking for easy removal. Remove the sachet at the end of cooking and discard.
Bouquet Garni
To make a bouquet garni, gather together 1 sprig thyme, 3 to 4 parsley stems, and 1 bay leaf. Wrap the herbs in 1 or 2 leek leaves or 1 celery stalk, and then tie together with a short length of kitchen twine. Remove the bouquet garni at the end of cooking and discard.
