Similar to a gougères recipe or a Brazilian cheese puffs, this Gruyère Cheese Puff Recipe is based on a simple choux pastry recipe, which uses flour, eggs, water, and butter. Substituting tapioca flour for wheat flour results in a gluten-free choux pastry (which is essentially what the Brazilian cheese puffs are), which is then elevated with the addition of Gruyère cheese and chives for this delightful and easy-to-make Gluten-Free Cheese Puffs Recipe.
