In the 1970s and 1980s, there was a brand of crisps called "Salt 'n' Shake" - a bag of plain crisps and a small sachet of salt. You opened the bag of crisps, found the sachet of salt, opened it, sprinkled some/all of it into the bag, held the top of the bag closed and shook the bag to mix the salt with all the crisps. These days, readymade, packaged crisps already have their flavour.
In BrE, your sentence would work if you removed "potato", leaving just "chips". Those are what are called "fries" in AmE.
