In a small saucepan, bring 4 ounces water to a boil and stir in 1/2 cup sugar. Simmer until dissolved, about 2 minutes. Add 1 tablespoon dried lavender or 1 lavender tea bag and remove from the heat. Steep the lavender in the hot syrup for 10 minutes. Strain the syrup into a heatproof jar, let cool and refrigerate for up to 2 weeks. Makes about 6 ounces.
