Article: Rinse a grapefruit and use your fingers or a knife to remove the peel. Then take a sharp knife and cut out the segments of grapefruit in between the white pith. Avoid including the white pith because this will make your smoothie bitter. Place the grapefruit segments into a blender and pour in 2⁄3 cup (160 ml) of orange juice. Add 1 peeled banana and 1 to 1 1/2 cups (150 to 228 g) of frozen strawberries. The frozen strawberries will thicken the smoothie. Use less of them for a thinner smoothie. Use your blender's smoothie setting or turn it on to blend until the ingredients are mixed. The smoothie should be completely smooth. If you still see chunks of frozen strawberries, you may need to turn off the blender and scrape down the sides before blending the mixture again. Remove the lid and pour the smoothie into 2 serving glasses. Consider garnishing the smoothies with sprigs of mint and serve them immediately. To store leftover smoothie, pour it into an airtight container and refrigerate it for up to 24 hours. Keep in mind that it may separate as it's stored, so you'll need to shake, stir, or blend it again.
