Product snapshot and key features

Gefen Corn Starch is described as 100% pure corn starch packaged in a 16 oz canister with a resealable lid for storage ease. The product carries kosher labeling and is marketed as a great flour alternative with the claim of twice the thickening power of flour.

Gluten safety and certifications

The product is labeled gluten-free, but there is no explicit gluten-free certification listed for this specific item (no GFCO/NSF certification evidenced).

Given these factors, celiac disease or gluten sensitivity readers should use caution.

Practical use, storage, and expectations

The resealable lid helps maintain freshness, and some buyers report convenience and reliable availability on Amazon. Price discussions exist, with some reviewers noting that it can be more expensive than grocery-store options, and flavor-related feedback is mixed.
