⭐ Rice Flour (Best Gluten-Free Option)
3/4 cup rice flour per 1 cup cake flourRice flour is gluten-free and has fine starch granules that gelatinize upon heating, providing moderate thickening. It lacks the gluten proteins found in cake flour, so it won't contribute to structure but can still thicken liquids effectively.
To avoid a gritty texture, sift rice flour before use and mix it into a slurry with cold water. Rice flour thickens quickly, so add gradually and monitor consistency.
The chili will be slightly less viscous compared to cake flour but remain smooth and cohesive, making rice flour a good option for gluten-free diets.
