Put the flour in a bowl with the salt on the side.
Make a well in the center of the flour and pour some of the milk into it.
Start stirring from the center to make a batter, gradually adding more milk to create a nice smooth dough, add the egg and honey and whisk everything well together.
If you have lumps, use an immersion blender.
Let the batter rest for an hour in a warm place.
Stir the dough loose and put it in a squeeze bottle.
