Knead all ingredients except for the milk and the grains or seeds for sprinkling with the dough hook or your hand. It is best to let it rise overnight or use chia seeds that have already swollen.
Shape the dough into 9 75g balls and flatten them a little on a baking sheet.
Brush the rolls with the milk and spread the grains, seeds, etc. on them, pressing them down lightly. Put the whole thing in the oven for about 15 minutes (use a stick sample).
