150g Mexican tarragon leaves
600ml white wine vinegar
Wash the tarragon leaves, pat dry with a tea towel then chop roughly. Stuff the Mexican tarragon leaves into a cleaned and sterilized jar then pour over the vinegar. Seal with a vinegar-proof lid then set aside in a sunny place to infuse for about 4 weeks, shaking the jar occasionally.
After this time, strain the vinegar through a fine-meshed sieve lined with muslin. Pour the liquid into a sterilized bottle (this is your Mexican tarragon vinegar). Add a fresh sprig of Mexican tarragon and seal securely.
