*I like the extra yolk in the dough but it's not a game changer. Some people like to brush the dough with only egg yolk for a more golden color. I use a whole beaten egg and I am happy with the color. You can also take any leftover beaten egg and brush the loaf a second time about halfway through baking.
**I have used O Organic olive oil, Lucini olive oil, Napa Valley Naturals, California Olive Ranch, and Chosen Foods avocado oil with success. Don't use a strong-flavored olive oil.
