Pao de Queijo - Brasilian Cheese Bread

I made this last night and they came out excellent as usual. It made 20 small cheese breads. The picture I am including was not taken by me....it's from the web. But mine looked sort of like this, but even better. These are so easy to make and so delicious!

2 cups manioc flour (can be found at any Asian or Brasilian market...it's super inexpensive, I buy a Vietnamese brand)

1 cup milk
1/2 cup butter (can also use canola oil, or combination of the two)
1 teaspoon salt
2 cups grated parmesan cheese or other hard cheese....stronger cheese is really nice. Adding more cheese doesn't hurt either...the cheesier the better.
2 eggs

Mix milk, salt and butter in a pot, and bring to a boil. Remove from heat, then add the manioc flour. Then add the cheese and eggs, kneed with your hands or spoon until it's smooth, then form balls (depending on how big you want the small breads to be) with your hands. Cook on greased baking sheet at 400 degrees until they are lightly browned and crispy on top, about 15-20 mins. Serve right away. They are delicious.

I personally love the texture of bread made with manioc flour, and ate lots of pan de yuca in Ecuador when I was there last year (same idea, but without the cheese).
