This is one of my favorite recipes from one of the delightful Brazilian restaurants near me. AND its gluten free.
Brazilian Cheese Puffs (Pao de Queijo)
1/4 Cup Canola Oil
1/4 Cup Water
1 Teaspoon Salt
1 Cup Tapioca Starch
1/3 Cup Plain Yogurt
1/2 Cup Grated Parmesan Cheese
1/2 Cup Grated Mozzarella Cheese
1/2 Cup Gruyere
Preheat an oven to 450 degrees F
Combine the canola oil, water, and salt in a saucepan and bring to a boil. Place the tapioca starch in a metal bowl; pour the oil and water mixture over the tapioca; mix thoroughly. Beat in the egg. Stir in the yogurt, Parmesan cheese, and mozzarella cheese. Pour the mixture into mini-muffin tins.
Place on middle rack of the preheated oven. Reduce heat to 350 degrees F (175 degrees C). Bake until slightly golden, 25 to 30 minutes.
