Place the peeled and quartered potatoes in a pot of water and add your salt.
Bring to a boil and cook for 15–30 minutes, or until very soft and fork-tender.
Drain the potatoes well (save a little water just in case), transfer them to a mixing bowl, and mash until smooth.
Let the mashed potatoes cool for 2–3 minutes to release steam.
Make the Garlic Paste and Assemble
Crush the garlic cloves along with the salt in a pestle and mortar until a smooth paste forms.
Add the garlic paste, lemon juice, white wine vinegar, and black pepper to the mashed potatoes. Start mixing the ingredients with a whisk until well combined.
Gradually drizzle in the olive oil, whisking continuously as you go, until the mixture is smooth and creamy.
Taste and adjust the seasoning. At this point, if you feel like the skordalia is a little too thick, you can add a splash of the reserved potato water to thin it out.
Transfer to a serving bowl, drizzle with olive oil, and garnish with parsley or fresh oregano.
Notes
Cooling the Potatoes: Do not add the garlic paste immediately after mashing the potatoes. It’s important to let the heat escape for a few minutes first to prevent the garlic from losing its bold flavour due to excessive heat.
Smoother Texture: For a velvety, luxurious consistency, pass the skordalia through a strainer after mashing. Use a large metal spoon to press the mixture through the strainer. This step takes a few minutes but makes a big difference if you want it smoother.
Garlic Paste Tip: Always use a pestle and mortar to crush the garlic for this recipe. A food processor won’t achieve the same paste-like texture needed. If you prefer, you can transfer the garlic paste to a food processor after it’s made to combine it with the other ingredients.
