01 - Combine milk and dried lavender in a small saucepan. Heat gently over low heat until just steaming, approximately 2 minutes. Avoid boiling to prevent scorching. Remove from heat and let steep for 5 minutes to extract floral essence.
02 - Pour the infused milk through a fine-mesh strainer to remove all lavender buds. Allow the strained milk to cool slightly before incorporating into the glaze mixture.
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 reaching a pourable consistency.
04 - Evaluate the glaze texture. Add additional lavender milk, one teaspoon at a time, to thin if needed. Alternatively, incorporate more powdered sugar, one tablespoon at a time, to thicken. Whisk thoroughly after each adjustment.
05 - Drizzle or spread the finished glaze over completely cooled baked goods such as cakes, scones, or cookies. Let stand for at least 10 minutes to allow the glaze to set properly before serving.
