Continue the shaping by pinching the head to create a tiny bulge: this is the bird's beak. Make a tiny cut into the beak with the scissors: now you have a singing bird. Using a toothpick, press peppercorns into the bird's face to give it eyes. Finally, stamp the tail with a fork.
Continue shaping the birds, then place them on a baking tray lined with baking paper.
Preheat the oven to 200 °C (400 °F).
Whisk together the egg yolk and milk and brush each bird bun with this egg wash. Make sure to reach the eyes, too, as they tend to fall out. In fact, I always push them in with the toothpick once again so they don't pop out while baking.
Bake the buns for 20 minutes until they turn golden brown, especially their heads.
Eat them warm on the same day or for breakfast the following morning.
