- 1 cup half-and-half
 - 1/2 cup vegetable oil
 - 1 pinch salt
 - 2 cups tapioca flour
 - 2 cups finely grated Pecorino Romano cheese
 - 2 eggs
 
- Heat half-and-half, vegetable, and salt together in a saucepan over medium heat; constantly whisk until mixture just starts to boil, about 5 minutes. Remove from heat and pour mixture into a large deep bowl.
 - Stir tapioca flour into half-and-half mixture using a wooden spoon. Mixture will thicken quickly. Cool to room temperature, about 20 minutes.
 - Preheat oven to 350 degrees F (175 degrees C).
 - Mix Pecorino Romano cheese and eggs into tapioca mixture using an electric mixer or by hand until dough has a paste-like texture. Continue mixing until dough is soft and stretchy. Roll dough into 2- or 3-inch balls and arrange on a baking sheet.
 - Bake in the preheated oven until cheese balls are puffed and hardened on the outside, 20 to 25 minutes. Serve warm.
