Step 5: Braid challah
Form half the dough into six balls or three balls, depending on the type of braid you’d like. Roll each ball into a strand about twelve inches long and one-and-a-half inches long. Line the strands up parallel to one another, pinching the ends together. Place the outside right strand over the center strands. Then take the left strand and do the same. Repeat the process starting over with the outside right strand. Continue this until you have a fully braided loaf. Keep your braiding loose as you go. The strands will need a little room to expand as they bake.
If you are making a circular loaf, twist your braids into a circle and pinch the ends together. With the second half of your dough, make another loaf the same way. Place your loaves on a greased baking sheet, leaving space in between.
