01 - Combine milk and dried lavender in a small saucepan. Heat gently over low heat until just steaming, approximately 2 minutes. Do not boil. Remove from heat and let steep for 5 minutes to extract floral essence.
02 - Pour the lavender-infused milk through a fine-mesh strainer to remove all buds. Allow the strained milk to cool slightly before proceeding.
03 - Place powdered sugar in a mixing bowl. Gradually whisk in 2.5 to 3 tablespoons of the lavender milk, adding lemon juice if desired. Continue whisking until completely smooth and pourable.
04 - Check glaze texture. If too thick, add more lavender milk 1 teaspoon at a time. If too thin, incorporate additional powdered sugar 1 tablespoon at a time until desired coating consistency is achieved.
05 - Drizzle or spread the finished glaze over completely cooled baked goods such as pound cake, scones, sugar cookies, or bundt cake. Let set for at least 10 minutes before serving to allow proper firming.
