Heat milk until steaming; pour into a large mixing bowl and let cool until lukewarm. Sprinkle in yeast and let stand until dissolved, 5 to 10 minutes. Whisk in 1 cup whole-wheat flour, cover with plastic wrap and set aside in a warm, draft-free place until foamy, about 1/2 hour.

Puree cottage cheese in a food processor. Stir the pureed cottage cheese, sugar, eggs, egg whites, 1/4 cup oil, lemon zest and salt into the yeast mixture. Gradually beat in, with a wooden spoon, the remaining 1 cup whole-wheat flour and enough of the all-purpose flour to make a soft, sticky dough. Turn out onto a lightly floured board, sprinkle raisins, currants, candied peel and almonds over it and knead until the fruits and nuts are evenly distributed and the dough is smooth and elastic, about 10 minutes, adding just enough additional all-purpose flour to prevent the dough from sticking. Place the dough in a lightly oiled bowl and turn to coat it with oil. Cover with plastic and let rise until doubled in bulk, 1 to 2 hours.

Punch the dough down and knead for about 1 minute on a lightly floured board. Divide it into 4 portions. Roll each portion into an 8 1/2-by-10-inch oval. With the side of your hand, crease the dough down its length just off center. Fold the smaller side over the larger and place the loaves at least 4 inches apart on two large, lightly oiled baking sheets. Brush the remaining 1 tablespoon of oil over the top of the loaves. Cover with plastic and let rise in a warm, draft-free place until almost doubled, about 45 minutes.

Preheat oven to 350 degrees F. Bake the loaves, one sheet at a time, until tops are golden brown and the bottoms sound hollow when tapped, 30 to 35 minutes.
