Dear Rabbi, 1. Can Kettle Krisps brand baked potato chips be used on Passover? It bears a Chaf-K hashgaha and the ingredients are: select russet potatoes, expeller pressed high monounsaturated safflower and/or sunflower oil and salt. 2. What about Roland brand white cooking wine, which bears an O-U and the ingredients are: chablis wine, salt, potassium sorbate, potassium metasulfite. Thank you for your time and hag sameach!
