The pungent, creamy benchmark of Greek meze: mashed russet potatoes or soaked rustic bread emulsified with fiery garlic cloves, Greek olive oil, and white wine vinegar.
Pound garlic cloves with a pinch of coarse sea salt in a mortar and pestle until completely puréed into a smooth paste.
Pass hot boiled potatoes through a fine potato ricer into a bowl. Let steam escape for 3 minutes.
Add the crushed garlic paste to the warm potatoes. Using a wooden spoon or hand whisk, alternate adding olive oil and wine vinegar in small increments, beating vigorously until an ultra-creamy, fluffy, ivory emulsion forms.
Season with salt and white pepper. Spread into a serving bowl, garnish with a Kalamata olive, and serve room temperature with fried fish or vegetables.
