Tarragon should be gathered on a dry day, just before the plant flowers Pick the green leaves from the stalks, and dry them a little before the fire. Then put them into a wide-mouthed stone jar, and cover them with the best vinegar, filling up the jar. Let it steep fourteen days, and then strain it into wide-mouthed bottles, in each of which put a large quantity of fresh tarragon leaves, and let them remain in the vinegar.
