Original visual accompanying the guide: Adjust Herb Seasoning for Storage Age and Cooking Time
Check the ingredient before increasing the amount
Dried herbs lose aroma with storage and exposure to heat, light and air. A weak-smelling jar may give a different result from a newly opened one even when the measuring spoon holds the same volume. Store herbs as directed and inspect their condition. Increasing the amount is not a solution for an ingredient that should be discarded.
Account for when the herb enters the dish
The recipe's timing affects the result. Some dishes give dried herbs time to hydrate during cooking, while delicate fresh leaves are added near the end. Retain the recipe's method when making a small substitution, and recognize that a numeric ratio does not reproduce the same aroma release or appearance.
Adjust in controlled steps
For a recipe asking for three teaspoons fresh chopped herbs, a three-to-one guide suggests one teaspoon dried. Start with the appropriate estimated amount, allow it to distribute, then taste when the dish is safe to taste. Record any adjustment for your jar and recipe. Avoid adding several unmeasured pinches at once; they make the next attempt hard to reproduce.
