"Skorthalia" Greek Garlic Dip/Sauce

1. Add the salt to a large pot of water. Peel the potatoes and boil in salted water until well done (easily pierced with a fork). Drain. Sprinkle the potatoes with pepper and mash. 2. In the blender bowl of the food processor (or with a hand mixer), purée the potatoes and garlic until well mixed, about 30-45 seconds. Still puréeing, slowly add the olive oil and vinegar, alternating between them, tasting as you go, until the mixture is smooth. Skorthalia should be creamy and thick. If it gets too thick, add a little cold water (not more than 1/4 cup). 3. To prepare by hand Mash potatoes with garlic. Drizzle in the olive oil and vinegar slowly, alternating between them, mashing well. Add pepper. This version may be grainier, but the taste is wonderful! 4. Note: Skordalia is a matter of taste. Some prefer a mild garlic taste, while others prefer a strong garlic taste. If the taste is too strong, adjust the quantities of potatoes or bread up a bit. If the taste is not strong enough, increase the garlic. 5. Additions In various regions of Greece, walnuts or almonds are added. If you like, add a cup of finely chopped walnuts or almonds to the food processor at the beginning, with the potatoes, and add the juice of a lemon to the liquids. The consistency will still be similar to thick ketchup but granular due to the nuts.
