Prepare the dough: In a mixer, combine water, yeast, and sugar. Mix until dissolved, then add flour and salt. Mix for 5-6 minutes.
Let the dough rise: Transfer the dough to an oiled bowl, cover, and let it rise until doubled in size, about 1 hour.
Shape the bagels: Divide the dough into 10 pieces, shape into balls, then form bagels by making a hole in the center of each ball.
Boil the bagels: Boil water with baking soda. Boil each bagel for 30 seconds on each side, then transfer to a baking sheet.
Bake the bagels: Brush each bagel with egg white, sprinkle with seeds, and bake at 180°C for 20-25 minutes until golden.
Serve: Slice bagels and fill with cream cheese, smoked salmon, dill, arugula, pepper, and balsamic cream.
