Measure 2 tablespoons lavender buds for each cup boiling liquid (usually water or milk). Steep for 30 minutes. Strain liquid. Lavender infusion can be used to flavor lavender lemonade, ice tea, cakes, cookies and sorbets. A lavender-milk or cream infusion can be used to make lavender crème brûlée, lavender ice cream, lavender cheese cake, lavender scones and more.
