Herbs:

When cooking with fresh and dry herbs, there is a general rule when it comes to the ratio of fresh to dry. Because dried herbs are generally more potent and concentrated than fresh herbs, you’ll need less — typically three times the amount of fresh herbs as dry. For example, if a recipe calls for 1 tablespoon of fresh oregano, you need only 1 teaspoon of dried, since 3 teaspoons equal 1 tablespoon.
