Two popular thickeners that often come up in discussions are yam flour and cornstarch. Both have their unique properties and benefits, but which one is better for thickening soups in 2026? This comprehensive guide will help you make an informed decision.

Understanding Yam Flour and Cornstarch

Before diving into the comparison, it's essential to understand what yam flour and cornstarch are.
