Fresh strawberries, soaked in light salt water for ten minutes. After rinsing, remove pedicels and control moisture. Prepare milk, strawberry ice cream and vanilla extract (vanilla extract can be added or not, it will taste better after adding it). Add strawberries, 10 ml milk, two spoonfuls of ice cream and a little ice cubes. Ice cubes should not be too big, and the length, width and height should be about 1~2 cm. Turn the blender to the second gear, stir 1 min, and put the milkshake in the refrigerator for freezing1min. Take it out and put a fresh strawberry on it, and you can start drinking!
