01 - Combine milk and dried lavender in a small saucepan. Heat gently over low heat until just steaming, approximately 2 minutes, ensuring the liquid does not reach boiling point. Remove from heat source.
02 - Let the lavender steep in the hot milk for 5 minutes to extract maximum floral flavor. Strain through a fine-mesh strainer to remove all lavender buds. Allow the infused milk to cool slightly before using.
03 - In a mixing bowl, whisk powdered sugar with 2.5 to 3 tablespoons of the lavender-infused milk. Add lemon juice if desired for brightness. Whisk vigorously until completely smooth and achieving a pourable consistency.
04 - Evaluate glaze thickness. If too thick, add more infused milk 1 teaspoon at a time. If too thin, incorporate additional powdered sugar 1 tablespoon at a time. Whisk thoroughly after each adjustment.
05 - Drizzle or spread the glaze evenly over completely cooled baked goods including cakes, scones, or cookies. Allow the glaze to set for at least 10 minutes before serving or storing.
