Stir together egg, butter, and half-and-half in a separate bowl. Add to flour mixture, stirring just until moistened. Gently fold in strawberries and Key lime rind. Spoon batter into paper-lined muffin pans, filling three-fourths full. Sprinkle each muffin with 1 tablespoon Streusel Topping. Bake at 375° for 25 minutes or until muffins are golden brown and spring back when lightly touched in the center. Cool muffins in pans 10 minutes; remove from pans, and let cool completely on a wire rack. Drizzle with Key Lime Glaze.
