Select the substitute that best fits your dish: spearmint for closest flavor, basil or lemon balm for raw applications, parsley with fennel for cooked dishes, cilantro with zest for a bright citrus touch.
Prepare the substitute by chopping fresh leaves; for parsley + fennel, measure and mix ground fennel evenly.
Use the indicated substitution ratios to replace fresh mint in your recipe, adjusting amounts as needed.
In cooked dishes, add parsley and fennel mixture during cooking; in raw dishes, add substitutes just before serving for best flavor.
Taste and adjust seasoning or herb quantities for desired balance and freshness.
