Add herbs at the same time as salt and pepper to meats, vegetables, sauces and soups. In long cooking foods, such as stews, add herbs during the last half hour of cooking time. Add herbs to juices or cold sauces well ahead of time and let stand overnight in order to develop the deepest flavor possible.
Guidelines for Using Herbs and SpicesBe familiar with each spice's aroma, flavor, and effect on food. Store dried herbs and spices in a cool place, tightly covered, in opaque containers. Don't use stale spices and herbs, and don't buy more than you can use in about six months.
