Make the Dough: Dissolve yeast in warm water. In a bowl, combine flour, salt, and malt powder. Slowly add the yeast mixture and knead for 10-12 minutes until smooth.
First Proof: Shape the dough into a ball, cover with a damp cloth, and let rise in a warm place for 45-60 minutes until doubled in size.
Shape the Bagels: Divide dough into 120 g portions. Roll into balls, then poke a hole in the center and stretch into a ring shape.
Cold Proof: Place shaped bagels on a tray, cover, and refrigerate overnight for better flavor.
Boil the Bagels: Bring water to a boil, add bicarbonate of soda and barley malt syrup. Boil bagels for 30 seconds per side.
Bake: Transfer bagels to a baking tray and bake at 220°C for 10 minutes until golden and crisp.
