Sir Kensington's Classic Mayo is made with 100% sunflower oil. At Sir Kensington's, we make real condiments from ingredients you can pronounce. We strive to source the best ingredients possible. All of our condiments and dressings are proudly Non-GMO Project Verified, and gluten free. We never use any artificial ingredients, colors, or preservatives. We believe if it's not food, it doesn't belong in our food. Our condiments and salad dressings are always in good taste, with good taste, for those with good taste. Sir Kensington’s started out of a belief that food and business had the power to create positive change in society. We also sought to create a food company that could be a model for change and stood for what we believed in - the power of food to connect people to each other, to nature, and to our creativity. Now we work every day to fulfill our mission: To re-imagine ordinary and overlooked with fearless integrity and charm. We started by making condiments and that's all thanks to our fellow food lovers who have taken a chance by joining us on the journey.
