Add the flour, yeast and sugar to a large mixing bowl. Add the salt but make sure that the yeast and salt do not touch. (Salt kills off yeast so it's best to keep them separate until you begin to mix everything into a dough.)
Add in 2/3 of the water and gradually add more until it forms a soft but not sticky dough.
Knead the bread for ten minutes or until it becomes smooth and elastic.
Oil a bowl with a little olive oil and place the dough in it. Cover with cling film or a clean tea towel. Leave it to rise in a warm spot free of draughts.
Once the dough has doubled in size, knock it back (Knock the air out of it by folding the dough repeatedly until the dough is smooth) and divide it into 7 equal-sized pieces. Shape these pieces into round balls.
Take a ball of dough and flatten it with the palm of your hand. Then make a hole in the middle with a finger, making sure that it goes all the way through.,
Enlarge the hole slightly by moving your finger in a circular motion to widen the hole. Place on a baking tray lined with baking parchment. Repeat with the rest of the pieces of dough .
Cover the uncooked bagels with a cloth and leave for about ten minutes for a second rise.
Heat a large pot of water. A soup pot is ideal as you can boil more bagels at the same time. Bring the water to a boil and then reduce to a simmer. Preheat the oven to 425F/220C/200C Fan.
Using a slotted spoon or slotted turner (fish slice) lower a bagel carefully into the water of the large saucepan. (I can get 4 comfortably in my soup pot) Fit in as many bagels as you can without crowding them too much. They need a little bit of space to expand and not touch each other. Cook for 2 minutes like this, then turn the bagels over carefully and cook on the other side for another 2 minutes. Then take them out and place them on the baking tray ready to go into the oven.
Do this with all the bagels.
If you are using sesame seeds, sprinkle the seeds over the bagels to create a nice topping.
Bake in the oven for eighteen minutes or until golden brown.
Remove from the oven and leave to cool on a cooling rack.
