Pour the water into a bowl and dissolve the yeast.
Then add the rye flour and the seeds (you can use any seeds you prefer).
Mix everything well.
Finally, add the wheat flour and salt.
Mix everything together.
Cover with plastic wrap and place it in the fridge until the next day.
Set the oven to the highest possible temperature.
Form approximately 12 rolls from the dough using two tablespoons and place them on a baking tray lined with parchment paper.
Place the tray in the preheated oven, reduce the temperature to 225 degrees Celsius (437 degrees Fahrenheit), and let the rolls bake until they sound hollow when you tap the bottom with your fingers. The baking time depends on your oven, but it takes about 15 minutes.
