In a mixing bowl, combine warm water, sugar, and yeast. Let it sit for about 5-10 minutes until frothy.

In a large bowl, combine flour and salt. Pour the yeast mixture into the flour mixture and stir until a dough forms.

Knead the dough for about 10 minutes until smooth and elastic.

Shape the dough into a ball and place it in a greased bowl. Cover with a damp cloth and let it rise for about 1 hour, or until doubled in size.

Punch down the dough and divide it into 12 equal pieces. Roll each piece into a ball and poke a hole in the center.

Place the shaped bagels on a parchment-lined baking sheet, cover with a cloth, and let them rise for another 30 minutes.

Bring a large pot of water to a boil and add baking soda. Boil the bagels for 1-2 minutes per side.

Preheat your oven to 425°F (220°C). Place the boiled bagels on a baking sheet, add toppings if desired, and bake for about 20 minutes or until golden brown.
