Reasons to love our Mayo

  • Our Mayo has staying power.

    Sir Kensington's mayonnaise lasts longer than homemade mayonnaise. There are a few factors that contribute to its longer life:

    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.

    Second, we add a combination of lemon or lime juice, vinegar, and citric acid (depending on the specific product) to reach a pH level that preserves the mayonnaise.

    Additionally, our mayonnaise is made in a food-safe facility that greatly reduces the risk of cross contamination.

  • Organic Certified Humane Free Range eggs or bust!

    We proudly use Organic 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. Certified Humane production never uses cages and ensures hens are provided the conditions necessary to engage in natural behavior so they can be the plucky animals they're known to be.

  • 10 out of 10 pregnant ladies agree, this Mayo is delish.

    The eggs in our mayonnaise are pasteurized, so our Mayo is safe to eat while pregnant. Learn more about the amazing eggs we use in our products here.
