1, making smoothies with a blender: dissolve a cup of sugar with 2 cups of water. Only by dissolving the sugar in advance will the smoothie not have a rough graininess. Pour sugar and water into a bowl and stir until all the sugar melts. Add essence and pigment. In order to imitate the taste of classic smoothies, add 1.5 teaspoon of essence, such as raspberry, strawberry, lemon, lime, coconut or vanilla essence, and at least 5 drops of food pigment to the white sugar water. Stir well with a long spoon. You can also add a little essence or pigment according to your own taste. Break the sugar water and 2 cups of ice cubes with a blender. Pour the prepared sugar water into the blender, and then pour 2 cups of whole ice. The high-power mixer can break the ice cubes to a greater extent, so as to obtain a smoother smoothie with a more delicate taste. Stir the mixture at high speed. The power of the mixer determines the mixing time. Usually, only a few clicks of intermittent stirring or continuous stirring for several minutes are needed, and ice cubes and water can present the texture of smoothies. Stir continuously until the ice cubes are completely crushed and the mixture reaches a satisfactory consistency.

2. Making smoothies with an ice cream machine: dissolve 1 cup of white sugar in 4 cups of water. Pour sugar and water into a bowl and stir well until the sugar particles dissolve. Doing so can make the taste of smoothies more delicate. Mix essence and food coloring. According to personal preference, mix 1.5 teaspoon of essence with 5 to 10 drops of pigment. If you want to make an excellent and delicious smoothie, you can refer to the following combinations of flavors and pigments. Pour the mixture into the ice cream machine and let the machine run for 20 minutes. Smoothies don't need to be frozen solid like ice cream. Just turn on the machine for 20 minutes after pouring the mixture. Spoon the smoothie into the glass. This method can make two large cups or four small cups of smoothies. Insert a straw and enjoy a delicious classic milkshake.

3. Make smoothies in the refrigerator: dissolve a cup of sugar in 4 cups of water. Pour sugar and water into a bowl and stir thoroughly until the sugar particles are completely dissolved. Dissolve sugar first to prevent frozen smoothies from eating granules. Mix essence and food coloring. Add 1.5 teaspoons of essence and 5 to 10 drops of pigment to the sugar water. Taste the taste, and add pigment and essence according to your own taste and preference. Pour the mixture into a shallow baking tray. The edge of the baking tray should be a few centimeters higher, so that the liquid will not overflow. Cover the baking tray with plastic wrap. If the baking tray has a lid, just cover it. The mixture was frozen for two hours and stirred every 30 minutes. Each stirring is to prevent the mixture from freezing into ice. The mixture began to approach the texture of smoothies. After about 3 hours, the smoothie formed.
