In a large bowl, combine warm water, yeast, and sugar. Let it sit for 5 minutes until frothy.

Add flour and salt to the yeast mixture and stir until a dough forms.

Knead the dough on a floured surface for about 10 minutes until smooth.

Place the kneaded dough in a greased bowl, cover, and let it rise for about 1 hour until doubled in size.

Preheat the oven to 425°F (220°C) and bring a large pot of water to a boil.

Punch down the risen dough and divide it into 8 equal pieces.

Shape each piece into a ball and poke a hole in the center to form a bagel shape.

Boil each bagel for 1-2 minutes on each side in the boiling water.

Remove the bagels and place them on a baking sheet lined with parchment paper.

Bake in the preheated oven for 20 minutes or until golden brown.
