Mix the milk, butter, yeast and maple syrup and warm up until everything is dissolved

Add flour and salt to the mixture and kneed into a dough

Cover and let rise for 1-2 hours in a warm place

Put the dough on a well-floured work surface and kneed again.

Part into 12 pieces and form balls

Flatten them a bit and then take the back of a wooden spoon to form the whole in the middle

Let re bagels rise again and in the meantime:

Preheat the oven to 180 degree

In a pan bring 1 liter of water mixed with the natron and salt to a boil, remove the pan from the stove and add the bagels (2-3 at a time)

Let them sit in the water bath for 30 seconds and make sure every side is covered

Take them out, drip off any excess water and put them on a baking tray

Sprinkle with salt, sesame or any seeds you like

Bake for 20-25 minutes (I usually bake them for 20 minutes, then turn them and bake for another 5 minutes)
