Homemade tincture of lavender
2 cups vodka
1/2 cup culinary lavender flower buds (e.g. Folgate or Royal Velvet, aka English)
parchment paper
large clean canning jar with a secure lid (I use an old 48oz honey jar)
1) Add the buds to the jar.
The best culinary lavender buds are well sifted, with hardly any brown bracts or stems remaining. Fresh means the buds are bright and not faded.
Don't even THINK about using sachet-grade lavender. If you use e.g. Grosso, it will turn out . . . gross, perhaps even toxic.
2) Pour the vodka into the jar.
3) Cut a generous piece of parchment paper for a lid liner. Wrap the parchment over the opening and screw on the lid over that. The parchment helps prevent any reaction between the contents and the lid's rubber and metal components.
4) Give the contents a whirl and store in a pantry away from light and heat for a month or so. At least weekly give it whirl to keep it mixed up.
5) Strain the contents through a sieve after a month and return the liquid to the same jar with the parchment between the lid and the jar for indefinite keeping on the shelf.
6) The tincture makes a refreshing cocktail in the summers over ice with some added sweetener and water, and is reminiscent of Ouzo or Anisette. Or jazz up your fresh-squeezed lemonade by adding some lavender tincture to it.
7) But mainly I use a tablespoon or two in hot tea made with honey and lemon in the colder months when I feel a cold or flu coming on. It usually stops the cold dead in its tracks if you begin with the tincture immediately on symptom onset, in my experience. This is not medical advice.
