To use a milkshake maker, fill the cup with the necessary ingredients. You may need to mix ingredients in the ratio 1 to 2 for milk to ice cream, respectively. After adding sugar and other desired ingredients, tilt the head of the machine back. Then lock the cup into the cup holder and submerge the blade and spindle with ingredients. Start the machine and move the cup up and down to blend the ingredients together. Ensure the blade is submerged throughout the entire process. When you finish blending the ingredients, turn the machine off, remove the cup and pour the drink into a tall glass. Enjoy!
