Dissolve the crumbled yeast in some warm water and mix it with 2 oz. of flour. Make rather solid dough and cut a cross-like incision on the top. Roll the dough in flour and put it into a bowl with 1 cup warm water for half an hour. Occasionally turn the dough when it floats to the surface.
Knead the remaining flour separately with 5 egg yolks, 4 oz. softened butter, sugar, the lemon zest, a pinch of salt and 3 oz. warm milk. Add the leavened dough and knead for 20 min. until the dough is smooth and rather compact. Let the dough rise in a warm place until increased by 1/3 third in volume. Knead the dough once more, adding half of the remaining softened butter in pieces. Put the dough back in the bowl to rise until doubled in size. Put the dough on the pastry board once more and knead in the remaining butter and the candied peel. Shape the dough like a dove, or place it in a dove-shaped mold, and let rise for half an hour.
Brush the dough with the remaining egg yolk, top the surface with almonds, pressing them in slightly, and then sprinkle with the granulated sugar crystals. Pre-heat the oven to 375°F and bake for 15 mins. Lower the heat to 325°F and cook for. another 20 mins.
