⭐ Arrowroot powder (Best Fat-Free Option)
1 tablespoon per 1 tablespoon cornstarchArrowroot powder is a starch extracted from tropical plants and functions similarly to cornstarch by thickening liquids through gelatinization. It activates at lower temperatures and does not require cooking, making it perfect for cold smoothies.
To use arrowroot powder effectively, mix it with a small amount of cold liquid before adding to the smoothie to prevent clumping. Avoid overheating as arrowroot can break down and lose thickening power if exposed to prolonged heat.
Compared to cornstarch, arrowroot provides a slightly clearer and glossier finish, enhancing the smoothie’s visual appeal and mouthfeel without imparting any off-flavors.
