- 1 cup packed fresh tarragon leaves plus sprigs for garnish, rinsed and spun dry
- 1 tablespoon freeze-dried green peppercorns, cracked coarse, plus whole peppercorns for garnish
- 2 cups white-wine vinegar
- Put the tarragon leaves in a very clean 1-quart glass jar and bruise them with a wooden spoon. Add the cracked peppercorns and the vinegar and let the mixture steep, covered with the lid, in a cool dark place for at least 4 days and up to 2 weeks, depending on the strength desired. Strain the vinegar through a fine sieve into a glass pitcher, discarding the solids, and pour it into 2 very clean 1/2-pint glass jars. Add the tarragon sprigs and the whole peppercorns and seal the jars with the lids.
