Peel the potatoes, cut into quarters and cover with a little salted water and cook until cooked. Peel the garlic cloves and mash them with the salt in a mortar.
Press the potatoes through a potato press and mix in the garlic and egg yolk. Pour in enough oil while stirring with a wooden spoon until a creamy mixture is formed. Season with lemon juice and pepper and mix in the coarsely chopped walnuts.
Recommended as an accompaniment to fried fish or fried eggplant and zucchini slices, or simply as a starter, only with white bread.
I also cooked garlic cloves and squeezed through with the potatoes. I left out the lemon juice because I didn`t have one.
