Cooking With Herbs: Flavor, Pairings & Substitutions

Fresh and dried herbs are not always interchangeable in the same way. Drying removes moisture and concentrates flavor, so a smaller amount of dried herb may season a dish than the fresh version. The exact swap depends on the herb, how old the dried jar is, and the recipe. Treat common conversion ratios as a starting point, then taste and adjust rather than assuming every herb behaves alike.

In U.S. cooking, cilantro usually means the fresh leaves and tender stems of Coriandrum sativum, while coriander usually means the dried fruit commonly called seeds. Names differ across countries, so a recipe's ingredient list and form matter. The leaves taste fresh and citrusy to many people; dried coriander is warmer, mild, and gently sweet. They are not direct flavor substitutes even though they come from one plant.

Thyme is a small-leaved, aromatic herb sold fresh or dried. Its flavor is often described as savory with a subtle minty or clove-like note. The leaves cling to thin stems, so a recipe may call for stripping them from the stem or adding a whole sprig and removing it before serving. If you chop the leaves, use a sharp knife and avoid crushing a large amount far ahead of time.

A homemade seasoning blend lets you adjust flavor without relying on a packaged mix. The American Heart Association notes that herbs, spices, citrus, and vinegar can add flavor in place of some or all of the salt. Packaged blends vary, so check the Nutrition Facts label rather than assuming a product is sodium-free. These blends are cooking ideas, not treatments for blood pressure or any other health condition.

Use clean, completely dry measuring spoons and jars. Label each jar with ingredients, especially if you cook for someone with allergies. Dried herbs gradually lose flavor; replace them when the aroma fades.
