In the bowl of your stand mixer fitted with a dough hook, dissolve the yeast, white sugar, and brown sugar in warm water and warm milk.
Allow to stand for 5 minutes.
Add the salt, olive oil, and the flour.
Begin at a low speed to bring the dough together. You can see in the pictures the progression of what the dough looks like as it kneads.
Knead dough at a medium speed for 5 minutes. After 5 minutes, your dough should look like picture 8. You can see that while the dough is not sticking to the sides of the bowl, it is still sticky.
Cover the mixing bowl with a light towel for the first rise.
As the dough rises over the next hour, you are going to knead it 3 or 4 times every 10 minutes. This is important because it continues to work the gluten in the dough for a chewy bread.
After that hour, cover the dough and allow it to rise until doubled (about 45 minutes).
NOTE - You can bake this bread in a regular loaf pan; however, for an authentic loaf, you'll want to order these long sandwich loaf pans. Dump the risen dough onto a lightly floured surface, shape it into a long loaf, and place it in a sandwich loaf pan that has been sprayed with non-stick cooking spray.
Cover and let rise until the edges of the loaf are about a ½ inch above the edges of the pan. (35-45 minutes)
Preheat the oven to 350 degrees when the loaf has risen halfway.
Bake the bread in the center of the preheated oven for 25 minutes.
Cool this delicious bread on a wire rack before slicing it or putting it in a bread bag.
