Make The Dough: Using a stand mixer fitted with the mixing attachment, combine the starter, water, and honey. Add the flour and salt. Combine to form a rough dough, then switch attachment to the dough hook. Run on low speed for 5 to 6 minutes to combine and knead.
Dough Rise: Cover and move mixing bowl to somewhere warm for dough to rise at room temperature for the next 10 to 12 hours. Now, I keep my house at about 70 degrees and I find my dough rises best in a bit warmer environment so I have been known to sit mine in my laundry room or even my garage work counter.. because, Florida!.
Shape Bagels: After your dough has doubled in size, turn your dough out onto a clean floured surface and shape into rectangle. Grab a pizza cutter or a sharp knife and divide your dough into 8 even pieces. Roll each piece into a ball and using your thumb or the base of a cooking spoon, make hole in the center of each and gently stretch to create the bagel shape.
Rest: Place on parchment-lined baking tray, cover lightly with a towel and let sit at room temp for 1 hour until poofy. Pre-heat oven to 425 degrees.
Boil: Bring water to a boil with sugar and salt. Boil bagels 2 minutes and 30 seconds on each side and then return them to the baking sheet.
Toppings: Once your bagels have all boiled and are cool enough to handle, whisk an egg white. Using a basting brush, lightly brush the top of each bagel with the egg white and then dip one side of your bagels in your preferred toppings and return them topping side up to the baking sheet.
Bake: Bake at 425°F until golden brown (20–25 minutes). Remove and enjoy.
