Dissolve the yeast, salt and sugar in the warm water. Stir in the eggs and flour, blending well. Cover and let rise in a warm area until bubbly and doubled in size, about 90 minutes.
Heat the oil in a 6-inch shallow fry pan with 1-inch sides to 375 degrees F.
Drop level tablespoons of dough into the oil, cooking 4 at a time. Fry each side until golden brown, about 2 minutes.
Drain well on paper towels, sprinkle with confectioners' sugar while hot. Serve warm.
