1. Dissolve yeast in 1/4 cup water and set aside. It will soon start bubbling.
2. In a large mixing bowl, combine the sugar, 2 cups of water, oil and salt. Mix.
3. Add the eggs and the yeast mixture and mix well.
4. Add 4 cups of flour, and mix well again. Add the remaining flour, 1 cup at a time, mixing well after each addition.
5. Turn out the dough onto a floured surface and knead knead knead. (If you are doing this in a mixer, just knead in the mixer.) When it is smooth and elastic, it is done. You may need to add a little extra flour or water to get it to that earlobe consistency. You can add the raisins here if you'd like.
6. Place in a lightly oiled bowl, cover with a damp towel, and let it rise until doubled in size.
7. Punch down, knead another few minutes, and return to the bowl for another rising.
8. Divide into thirds (by cutting with a knife; don't pull), and shape into loaves.
9. Heat oven to 350°F
10. Place each loaf in a prepared pan or on a cookie sheet lined with parchment paper. Brush the tops with the egg/water mixture, and sprinkle with seeds if you wish.
11. Bake for about 45 minutes. When done, the loaves will sound hollow when tapped on the bottom.
