01 - Combine whole milk and dried culinary lavender in a small saucepan. Heat over low heat until just steaming, approximately 2 minutes. Remove from heat and let steep for 5 minutes to extract floral flavor.
02 - Pour mixture through a fine-mesh strainer into a heat-proof container, discarding lavender buds. Allow milk to cool slightly before using.
03 - Place sifted powdered sugar in a mixing bowl. Gradually whisk in 2.5 to 3 tablespoons of lavender-infused milk and lemon juice until smooth and pourable.
04 - Check glaze texture. If too thick, add additional lavender milk 1/2 teaspoon at a time. If too thin, incorporate more powdered sugar 1 tablespoon at a time until desired spreading consistency is reached.
05 - Drizzle or spread glaze evenly over completely cooled baked goods including cakes, scones, or cookies. Let stand at room temperature for at least 10 minutes until glaze sets and firms.
