Weigh all ingredients separately
Place all the ingredients, except for the oil in your stand mixer.
Using your dough hook mix until all the ingredients are incorporated and the dough starts to feel elastic
Then turn the stand mixer to low speed, and slowly start adding the oil. If you add too much it will start splashing, so make sure you add it slowly
Once all the oil has been incorporated into the dough stop the mixer and scrape the dough out onto your working table.
Divide the dough in 3 pieces of 150 grams each using your digital scale.
Shape each piece into a log of 20 inches long.
Braid the dough, making sure its not too tight to leave space for the dough to rise.
Mix 1 egg with a brush, and use it to egg wash the dough.
Let the dough sit in a warm spot and egg wash it often to prevent the dough from creating a skin (as it wont allow the dough to rise properly)
Once the challah has doubled in size preheat the oven at 350°F
Egg wash again before baking and bake at 350°F for 30 minutes.
Enjoy!
