Preparation
Preheat oven to 350 degrees F. Whisk flour, baking soda, and salt together in a bowl.
Mix 1½ teaspoon of grapefruit juice into milk in a small bowl, and set aside for about 5 minutes. In a large bowl, mash the butter with ¾ cup of sugar until creamy and well combined, and beat in the egg and grapefruit zest until thoroughly combined.
Beat the milk into the butter mixture about 2 tablespoons at a time, alternating with the flour mixture, until the dough is smooth. Drop by teaspoons onto ungreased baking sheets, about 2 inches apart.
Bake in the preheated oven for 12 to 14 minutes, until set and very lightly browned. Cool on racks.
Make glaze by mixing ¾ cup sugar with ¼ cup grapefruit juice. Brush glaze onto cooled cookies; let stand until glaze is set.
