Verdict

Bob’s Red Mill Arrowroot Flour is a reliable, versatile, and clean alternative to cornstarch, perfect for cooking, baking, and a variety of DIY personal care projects. If you’re looking for an allergy-friendly, non-GMO thickener with multiple household uses, this is a great choice that delivers consistent results. For those seeking a similar product with broader availability or lower price, cornstarch is the usual go-to, but if you want the added benefits and ethical sourcing, this is the flour to grab.
