Buying Guide
- What size should I buy? Consider household size and cooking frequency. Singles may prefer 6.5 oz to 16 oz, while larger families benefit from multi-pack options like 16 oz x 2 or 28.2 oz x 2.
- Gluten-free needs? If gluten sensitivity matters, choose clearly labeled gluten-free brands such as Argo or Klass. Look for “gluten-free” on the packaging.
- Non-GMO considerations? If you prefer Non-GMO options, Clabber Girl provides a Non-GMO choice in a compact size.
- Versatility? Some corn starches are marketed for non-food uses (odor elimination, dry shampoo). Use only for culinary purposes unless the product explicitly allows multi-use.
- Storage? Store in a cool, dry place and keep packaging sealed to prevent clumping or moisture exposure.
FAQ
- Is corn starch the same as cornstarch? Yes; corn starch is the same product, often called cornstarch in the United States. It thickens sauces and gravies when heated with liquid.
- Can corn starch be used for baking? It can be used to lighten cakes or improve texture in certain recipes, but it is typically used as a thickener rather than a primary flour substitute.
- Is all corn starch gluten-free? Most corn starch is gluten-free; verify on the package to ensure no cross-contamination during processing.
- How should I store corn starch? Keep it in a cool, dry place in a sealed container to prevent moisture absorption and clumping.
- What’s the best option for a small kitchen? A compact 6.5 oz or 16 oz box is practical for limited storage and infrequent use, with a smaller footprint and easy handling.
- Are multi-pack options worth it? If you use corn starch regularly, multi-pack options save trips to the store and may offer better value per ounce.
