What do you when all the cookie mixes mix taste and smell like metal?

- Rancid nuts or chocolate chips: If the cookie mix contains nuts or chocolate chips, check the expiration date and make sure they are not rancid. Rancid nuts or chocolate chips can give off a metallic taste or smell.

- Metal utensil: If you used a metal utensil to stir the cookie mix, it's possible that the utensil reacted with the ingredients in the mix, causing a metallic taste or smell.

- Metal pan: If you baked the cookies in a metal pan, it's again possible that the pan reacted with the ingredients in the mix, causing a metallic taste or smell.

- Old baking powder or baking soda: If the baking powder or baking soda in the cookie mix is old, it can give off a metallic taste or smell.

Solutions:

- Use fresh ingredients: Make sure all the ingredients in the cookie mix are fresh, especially the nuts and chocolate chips. Check the expiration dates on the packages.

- Use non-metal utensils and pans: Use wooden or plastic utensils to stir the cookie mix, and bake the cookies in a non-metal pan.

- Use fresh baking powder and baking soda: Replace any old baking powder or baking soda with fresh ones.

- Contact the manufacturer: If you've tried all of the above solutions and the cookie mixes still taste or smell like metal, contact the manufacturer. They may be able to provide you with further assistance or a replacement product.
