In a large stand mixer, combine the instant yeast, sugar, sea salt, water, and bread flour.
Using the dough hook, knead the dough for 8-10 minutes.
Cover the bowl and allow to rise for 1 hour.
After the dough has risen, punch down the dough and remove from the bowl. Separate the dough into 15 equal pieces and roll each into a tight ball. Place the dough balls onto a parchment lined sheet pan and allow to rest for 10 minutes.
Add water and maple sugar to the stock pot and bring to a boil.
Preheat the oven to 425℉.
Using a chopstick, poke a hole through the center of a dough ball and spin the dough to make the hole in the center larger. Using your hands, stretch the bagels so that they keep the round shape, but the center hole is about 2 inches in diameter.
Place the bagels (about 4 at a time) into the boiling sugar water and boil each side for 1-2 minutes. The bagels can be flipped and removed from the water using the slotted spoon.
Remove the bagels from the water to the parchment paper lined sheet pans. Brush each bagel with egg wash and generously sprinkle with topping (ie: everything bagel seasoning, sesame seeds, poppyseeds)
Bake for 20-22 minutes or until the internal temperature is 200℉.
Allow to cool on a cooling rack for 15 minutes before serving.
