⭐ Cornstarch (Best Nut-Free Option)
Use 1 tablespoon of cornstarch per 1 tablespoon of arrowroot powderCornstarch is a fine starch derived from corn and acts as an effective thickening agent by gelatinizing when heated with liquid. In risotto, it helps achieve the desired creamy consistency without cloudiness or graininess.
To use cornstarch effectively, dissolve it in a small amount of cold water before adding to the risotto near the end of cooking to prevent clumping. Avoid prolonged boiling after adding to maintain the glossy texture.
Compared to arrowroot, cornstarch may slightly reduce the clarity of the sauce but will preserve the smooth mouthfeel and creaminess essential to risotto.
