Peel 4 medium sized potatoes, then cut each one into 8 evenly sized pieces, I like to cut them in half and then cut each half into quarters, add the cut potatoes into a colander and rinse under cold water, then add them into a stock pot, making sure they´re all in a flat layer, fill with cold water to about ½ inch (1.25 cm) above the potatoes, season generously with sea salt and heat with a high heat
Meanwhile, heat a small fry pan with a medium heat and add in 2 tbsp extra virgin olive oil
While the oil is heating, separate the cloves from a head of garlic and remove the skins from the cloves
Add the peeled cloves of garlic into the hot olive oil, mix continuously so the cloves of garlic evenly sautée, after 3 minutes and the cloves of garlic are lightly browned, do not over cook, remove the pan from the heat, add the cloves of garlic into a mortar and reserve the olive oil, add in 2 tbsp finely chopped chives into the motar and a pinch of sea salt, using a pestle pound down on the ingredients until you form a paste, set aside
About 23 to 25 minutes after turning on the heat on the potatoes, they should be perfectly cooked, just pierce them with a toothpick, if it easily goes in, they are ready, do not over cook, drain the potatoes into a colander and let them rest for a couple minutes, then add them into a large bowl, add the reserved garlic mixture and using a potato masher, gently mash the potatoes until you end up with a smooth texture with no lumps, do not over mash the potatoes, otherwise they will get gluey
Then add in ½ cup Greek yogurt at room temperature, season everything with sea salt and a generous portion of freshly cracked black pepper, using a large spoon mix everything together until well combined, remember to be gentle and do not over mix, taste as you mix to ensure seasonings are correct
Transfer the mashed potatoes into a large shallow bowl, using a spoon pour the reserved garlic infused olive oil over the mashed potatoes, sprinkle with finely chopped chives, enjoy!
