01 - Combine milk and dried lavender in a small saucepan. Heat gently over low heat until just steaming, approximately 2 minutes, taking care not to boil. Remove from heat and allow to steep for 5 minutes to extract floral essence.
02 - Pour the lavender milk through a fine-mesh strainer to remove all buds. Let the strained milk cool slightly before incorporating into the glaze base.
03 - Whisk powdered sugar with 2.5 to 3 tablespoons of the lavender-infused milk in a mixing bowl. Add lemon juice if using. Continue whisking until completely smooth and reaches a pourable consistency.
04 - Fine-tune the glaze thickness by adding more milk to thin or additional powdered sugar to thicken as needed for your intended application.
05 - Drizzle or spread the finished glaze over cooled baked goods. Allow to set for at least 10 minutes before serving to achieve proper coating consistency.
