One of my favorite seasonings is Basil Flower Vinegar, it adds a great deal of flavor without much being used, and is good in any
tomato dish as well as in salad dressings and sauces or on summer squash and
mushroom stir-fry. Making the vinegar itself is the hard part, but any good sweet red wine in a tun with an aerator stone and some vinegar bacteria ("Mother" in technical terms) will produce good Balsamic vinegar in time. I'm going to list recipes below which utilize the vinegar once it is made.
Basil Flower Vinegar #1
12 oz Balsamic Vinegar
1 loose cup of flowers of Siam Queen or Persian Basil
1 whole Clove
Basil Flower Vinegar #2
12 oz Balsamic Vinegar
1/2 loose cup Siam Queen or Persian Basil flowers
1/2 loose cup Sweet Basil flowers
