The Take
Blue Plate Real Mayonnaise is soybean oil in a jar with egg yolks added for Southern branding and a thin layer of perceived quality. The 1927 recipe angle sells nostalgia, but the first ingredient reveals the same seed-oil base that defines most commercial mayo.
Buyers reach for it to signal regional authenticity or homemade taste on sandwiches and salads. In practice it functions as another ultra-processed spread loaded with additives that modern seed-oil skeptics actively avoid.
The Verdict
The egg-yolk detail is real but irrelevant next to soybean oil as the dominant ingredient. Natural flavors and EDTA push it further into processed territory that ancestors never encountered on their sandwiches.
Skip it. Buy Primal Kitchen Avocado Oil Mayo — actual fat upgrade, no soybean sludge.
