Start by making the yeast work. Mix some warm water, sugar, and yeast in a bowl. Wait for 5 minutes until it gets frothy.
Combine the wet ingredients:
In a big bowl, mix the eggs, oil, and salt. Add the yeast mixture that is already working to this and mix thoroughly.
Add the flour:
Slowly pour the flour into the bowl, one cup at a time, and keep mixing. Continue to add more ingredients to the dough until it is firm enough to be kneaded.
Kneading:
Place the dough on a surface with flour and press and fold it for about 10 minutes until it feels smooth and stretchy. Add more flour if the dough is too wet.
First rise:
Put the dough in a greased bowl, cover it with a clean cloth, and let it sit in a warm place for 1-1. 5 hours or until it gets twice as big.
Split and twist together:
After letting it rise, press the dough down and separate it into the amount of strands you want to braid. Twist the strands together and tuck the ends in for a tidy look.
Second rise:
Let the dough with the braid on it sit for another 30-45 minutes, covered until it gets bigger.
Preheat and brush:
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Whisk an egg and spread it over the braided Challah bread for a nice, shiny surface.
Baking:
Put the Challah in the hot oven and cook for 25-30 minutes or until the top is golden brown and sounds empty when tapped.
Cooling:
Let the Challah bread cool on a rack before cutting it.
