Very Soft Focaccia

Why I Love This Recipe
Ingredients You'll Need
500 g (17.5 oz) bread flour
100 g (3.5 oz) durum wheat flour
6 tblspoons potato flakes (instant mashed potatoes preparation)
10 g yeast
450 ml lukewarm water (about 1/8 gallon or 16 oz)
1 tblspoon sugar
2 teaspoons salt
3 tblspoons olive oil
+
2 tblspoons olive oil
2 tblspoons water
1-2 tblspoons kosher salt
cherry tomatoes, onion or other vegetables as desired
Directions
Sift together the flours and mix with potato flakes, sugar and yeast.
Make a well in the middle and start adding water, mixing in the dry ingredients. Half way through add the salt as well.
When you have mixed in all the flour, proceed kneading on a floured surface to get soft and elastic dough. Depending on the humidity conditions and the type of potato flakes, you may need a little less or a little more water.
Place the dough in an oiled bowl, cover and let rest for about 1 hour in a warm place (I usually place the bowl into a cold oven or microwave oven, it raises better and doesn't get dry).
Put the dough into an oiled baking tin (large) and spread with your hands only to about 1/2" thick. Let it rest again, covered, for 1/2 an hour.
Mix oil, water and kosher salt and brush well the whole surface of your focaccia.
Add tomatoes, sliced onion or whatever else you want (I had some leftover baked potatoes from the previous day, so I sliced and added those as well), and bake in the oven preheated to 180°C (350°F) for about 20 minutes.
