01 - Pour milk and dried lavender into a small saucepan. Heat over low heat, stirring occasionally, until the mixture begins to steam. Do not boil. Remove from heat immediately, cover, and let steep for 5 minutes to extract maximum floral flavor.
02 - Set a fine-mesh strainer over a small bowl or measuring cup. Pour the lavender milk through the strainer, pressing gently on the buds with a spoon to extract all liquid. Discard the spent lavender buds. Allow the infused milk to cool for 2-3 minutes.
03 - Place powdered sugar in a medium mixing bowl. Create a well in the center and add 2.5 tablespoons of the warm lavender-infused milk along with lemon juice. Whisk vigorously until completely smooth and free of lumps.
04 - Check glaze thickness. It should coat the back of a spoon and flow slowly. If too thick, add remaining lavender milk 1/2 teaspoon at a time. If too thin, incorporate additional powdered sugar 1 tablespoon at a time until desired consistency is achieved.
05 - Pour or drizzle the finished glaze over completely cooled baked goods such as cakes, scones, or cookies. Work quickly as the glaze begins to set upon contact. Let stand at room temperature for at least 10 minutes to allow the glaze to firm before serving or storing.
