Let dough rise in a warm place for minimum 5 hours or until doubled.
Kned the dough for about 5 minutes until it become like playdoh. If sticky, sprinkle a bit of of flour on the dough.
Cut the dough into 8 equal size pieces.
Shape them into bagels by poking a hole in each and stretching it out a bit.
Put the bagels on parchment paper on a large baking sheet/tray giving enough space to rise and spread more. Leave it for around 30-60 minutes.
Bring a large pot of water to a boil. Add 1 tablespoon baking soda. Boil the bagels for 30 seconds per side, using a slotted spoon to flip them. Don't overcroud them so they don't stick together and you can flip them easily. Do this in two batches if you have to.
Remove from the pot gently and sprinckle with seasoning while they are still wet.
Bake at 430F (220°C) for 25-30 min or until golden brown on the outside.
Cool on a wire rack.
