Peel the potatoes and cut into cubes.
Bring a pot of water to a boil, add 3/4 teaspoon salt and when the water is boiling add the potatoes. Boil until they are mash-able, approximately 15 minutes (this will depend upon the size of your potato chunks).
While the potatoes are boiling, prepare your garlic. Peel the garlic, check each clove for any green parts and remove them. Then combine the garlic with 1 teaspoon of salt. Place the garlic and salt in a mortar and pestle and turn it into a paste.
When the potatoes have boiled, mash them. If you need to add liquid in order to make them creamier and easier to mash, add 1/4 cup of the water that they were boiled in.
Allow potatoes to cool.
In a standing mixer fitted with the whisk attachment, combine the cooled mashed potatoes, garlic paste, red wine vinegar and vegetable oil. Whisk together for 3 – 5 minutes on medium speed until all of the ingredients are well combined.
Enjoy!
