Combine yeast with 1/2 cup of warm water, then set aside until foamy.
Combine flour, salt, and sugar in a medium to large bowl.
Use a whisk to mix all the dry ingredients.
Once the yeast mixture is ready, pour it into the bowl.
Add melted butter.
Mix and knead until you get a smooth dough.(NOTE: Manually kneading with your hands typically takes 8 to 10 minutes.) Divide the dough into 6 equal parts.
Form each portion into a disc and place them on a baking tray lined with parchment paper.
Cover with a kitchen towel and set aside until they puff up --- generally takes 45 minutes for me.
Preheat your oven to 180°C (350°F).
Using a pastry brush, coat each Chilean country bread with milk.
Use a fork to create holes in each disc.
When the oven is ready, place the baking tray in the oven.
Bake for 25 to 30 minutes or until they turn golden.
Remove from the oven and transfer to a cooling rack.
Serve and enjoy your freshly baked pan amasado!
