Ever find that your powdered sugar has a soapy taste and any idea why this would be the case? I;ve noticed it particularly with one brand, but I'm not sure it's brand-specific. Thanks.
Powdered sugars have anti-caking agents. It wouldn't surprise me if they varied enough between brands that you could detect them.
Powdered sugar contains cornstarch. Not sure why, but maybe that's the culprit? Curious what the ingredients are in that one particular brand.
i mean not sure why it would taste soapy! cornstarch is anti-caking, like Grenstuff said, making the 10x fluffy and light.
