Put flour, honey, and yeast in the bowl of a standing mixer with a dough hook, put flour, honey, and yeast (or in a large mixing bowl if kneading by hand), and mix on low speed for about a minute.
Let the mixer work while slowly adding the oil.
Slowly add water and mix to form the dough .*Because each flour is different, stored differently, and has different absorption capacities, the amount of liquid will almost always change. Even if you always use the same flour, it may be that on different days, the flour will absorb more liquid than before. So, start with half a cup of water and gradually add enough until the dough is soft but not sticky. Dough that lacks liquid will be stiffer and much less comfortable to work with. The water temperature should be warm.
Increase the speed to medium. Add the salt and knead for 10-15 minutes (It helps the gluten form and the dough to be elastic with better structure).
Grease the dough with a little bit of oil, cover with a kitchen towel and let the dough rise until doubled (place the bowl somewhere warm).
Separate the dough into equal pieces, depending on your braiding.
Roll each piece of dough into a long rope. Braid the ropes.
Line a baking sheet with parchment paper and place the Challah on it.
Place the pan somewhere warm, cover with a towel, and let it rise until puffed, about an hour.
Heat the oven to 400°F/200°C. When ready to bake, whisk the egg with a tablespoon of water and brush it all over the Challah.
Slide the Challah on its baking sheet into the oven and bake for 25 to 30 minutes. The Challah is done when it is a rich golden brown and registers 190°F/90°C in the very middle with an instant-read thermometer.
Whisk the honey with a tablespoon of water and brush it all over the Challah when it comes out of the oven.
Let the Challah cool on a cooling rack. Enjoy!
