You only need a small amount of cooked or steamed potatoes and then let them cool.
Add the cooled potatoes, potato milk, mango chunks or ripe banana, and salt to your blender.
Blend until you reach a smooth, even consistency.
Add honey a teaspoon at a time until you reach the desired sweetness.
Pour in the lecithin granules, then blend.
Enjoy.

Notes
If you wish to give your Potato Milk Shake some more flavor and texture, feel free to add either 1 ripe banana, half an avocado or 1 cup of mango chunks to the list of ingredients.
