A taste test of store-bought mayonnaise brands was conducted, with the number of brands tried varying in reports, ranging from 7 to 16, although most outlets agree that 9 brands were sampled. The results of the test are inconsistent, with some outlets claiming a clear winner and others unable to pick just one. The test appears to have been part of a larger series of condiment taste tests, with similar tests also conducted on other dips and dressings.
