Place the ingredients into the bread machine pan, starting with the liquid ingredients listed first.
Place the flour on top of the liquid ingredients and create a small well in the flour.
Nestle the salt and yeast in the flour well, then close the lid.
Set the bread machine to bake using the basic cycle and medium crust setting (or equivalent settings on your machine).
Press start and allow the machine to cycle.
Optional: During the final rise (after the last punch down but right before baking), open the lid and brush the top of the loaf with egg white and sprinkle with poppy seeds. Feel free to skip this step for a complete hands-off bread machine challah.
For best results, remove the bread from the pan and allow it to cool completely on a cooling rack before cutting.
Notes
The original recipe specified bread flour, but I've had excellent results using King Arthur Flour All-Purpose. Choose a higher gluten flour if you have it available. The recipe also suggested adding 2 tbsp vital wheat gluten, but I have omitted it as it's hard to obtain. Add it if you'd like a higher rise.Choose either 1 tablespoon of honey or 2, based on your tastes. The original recipe suggests 1 1/2 tablespoons but I like it both as a slightly more savory loaf with a bit less, and a sweeter loaf with a bit more. This recipe can also be used as a dough recipe, setting the machine to the dough-only cycle and then removing the dough to shape and rise on the counter. That's an easier way to prepare a braided challah loaf without having to hand knead.For a 1 1/2 pound loaf, use the following ingredient quantities (but follow the same instructions):
