I got this recipe from a friend. It is very popular here in Brazil. You can have different shapes with the dough, kids love it. We call it "pão de queijo" if cheese balls or "biscoito" when they are rolled. This is a "gluten-free" recipe.
1 pound/500 g tapioca starch
1/3 cup milk
1 cup milk
1 cup canola oil (I used 2/3 cup)
1 tablespoon salt
1/2 cup grated cheese (I do not add cheese)
1) In an non-metallic bowl mix well the tapioca flour and 1/3 cup milk with your hands.
2) In a pan, bring to boil the 1 cup milk, salt and oil and add to the tapioca mixture using a wooden spoon. Add the eggs one at a time and then the grated cheese (or skip the cheese).
3) Make cheese balls or roll them into lines about 2 inches/5cm with your hands and bake them for 20/25 minutes at 400◦C/200◦C. They will be slightly golden on the outside. Cool them on a rack.
