Certified Humane Free Range eggs or bust! We proudly use Certified Humane Free Range eggs in our products, sourcing them from cooperatives of family farms in and around the Eastern Iowa region. These standards are more well-defined than the USDA Free Range definition, specifying the amount of time and space hens need access to the outdoors. The Sir Kensington’s mayonnaise manifesto? Source carefully, prepare artfully, and apply liberally. The reign of unremarkable mayonnaise is at an end. We source the finest certified humane, free-range eggs, smooth natural oils, and aromatic seasonings to create a properly standout specimen that promotes confident dipping. We use pasteurized egg yolks to reduce the risk of food-borne illness. Most grocery store shell eggs are not pasteurized. Because mayonnaise is not cooked, pasteurized eggs ensure the safety and stability of the eggs in our mayonnaise. All Sir Kensington's condiments and dressings are proudly Non- GMO Project Verified, Gluten free, Soy free, Paleo diet friendly, and Kosher.
