Sir Kensington’s Condiments

When Malcolm Gladwell wrote a 2004 New Yorker story about how its impossible to compete with Heinz ketchup, Brown University seniors and co-founders of Sir Kensington’s Scott Norton and Mark Ramadan took it as a dare. From the beginning, Sir Kensington’s saw opportunity in the fact that Heinz defined the ketchup category— and all other ketchup brands copied their packaging, positioning, texture, and taste. But Norton and Ramadan’s motivation was to create a product that was dramatically different and better, and started tinkering with recipes in their off-campus apartment and even hosted “Ketchup-Tasting Parties” to poll their friends with blind taste tests. When they nailed the recipe, they set out to position the packaging and brand in a distinctive way.

Today,  Sir Kensington’s is a saucy yet dignified brand of New York-based gourmet condiments that offers an all-natural, GMO-free alternative to the ketchup status quo. Sir Kensington’s crushed ripe tomatoes balance a blend of seasonings that resulted in a distinct flavor that relied less on sugar and salt and more on quality, texture, and flavor. At last, progress—a ketchup that could compete with Heinz that requires no apology.

Chapter 1: The Story of Sir Kensington

Born to a merchant family in Great Britain, Sir Kensington attended Oxford University for his course of undergraduate study, attaining degrees in mercantile trade, agronomy, and culinary arts. Inspired by herbal curiosities brought west by sail, he developed a wanderlust and shifted his focus to the Orient.

Upon joining the National Geographic Society and Guild of Pepperers, he accepted a post in Constantinople in the service of Her Majesty, advising the British East India Company in speculation of rare spices. Upon his return to England, he authored and defended his groundbreaking thesis, A Most Seemly Union: Byzantine Gastronomy & the Delightful Marriage of Greek and Roman Influence, 330-453, to earn a doctorate from Cambridge.

The commercially savvy Sir Kensington then founded and developed a reinsurance concern later acquired by Lloyds of London, thusly freeing him to focus on his true calling: the evolution of cultural understanding. He began hosting summits and salons with various luminaries from across the Old and New Worlds alike, quickly realizing that the secret to a pleasing gathering was the gastronomic fuel on which it ran.

Chapter 2: The Recipe

At one such summit, the emperor of Japan presented the assembled guests with tender slices of Wagyu beef. Upon being served, Catherine the Great of Russia leaned toward Sir Kensington to request a side of ketchup.

Baffled yet intrigued by the request, Kensington ventured to the kitchen, where he could find nothing acceptable for such a dish or such a diner. Undeterred, he set about to create, on the spot, a ketchup that would forever bear his name. And so the knowledgeable knight became a ketchup king, forever to be fondly favoured for his flavourful findings. He remains to this day the only commoner to have been invited to Buckingham Palace for three meals in a single day.

Chapter 3: The Revival

Sir Kensington's spice chronicles were feared lost until 2008, when Brown University students Scott Norton and Mark Ramadan uncovered them, filed away and forgotten, in the library's special collections.

Enchanted by the simplicity of the lost recipes, Scott and Mark vowed to revive ketchup in the Sir Kensington tradition. A great success, the experiment yielded the first of many batches of this rare and exceptional formula. Uncommon, healthful, and painstakingly prepared, it could bear no other name than that of Kensington himself.

Today, Sir Kensington's is headquartered in New York City's SoHo district. The company continues its tradition of daring innovation in order to offer its faithful clientele wholesome, delightful alternatives to the status quo. Sir Kensington would be proud.

And so a most extraordinary tale reaches its end.

100% of  Paleo Foundation revenue is generated through certifications.  We do not accept donations, corporate sponsorships, or financially benefit from the sales of any certified products, product giveaways, or partnerships with industry contacts or retailers for the purpose of maintaining the integrity of an impartial certification standard. 

Certified Paleo logo Certified Paleo:

Each certification program has a different set of standards.  Certified Paleo is the Paleo Foundation’s first, most popular, and highest level of certification for Paleo-compliant products.  Certified Paleo Products are products that contain Paleo ingredients, but may have some 21st-century processing or packaging methods allowing for shelf stability.


Grain Free Gluten Free Certified LogoGrain-Free Gluten-Free: 

Grain Free Gluten Free Certified products are gluten-free and do not contain any grains of gliadin competitive residues.  All Grain-Free Gluten-Free products have undergone two rounds of audits, including lab tests, and a final review to become approved for the Grain-free Gluten-free Certified Program. 



Keto Certified LogoKeto Certified: 

The ketogenic diet is a restrictive, demanding diet that can be difficult to maintain, and tolerability of the ketogenic diet is the single most important factor limiting individual acceptance for initiation.  Therefore, improving the tolerability of the ketogenic diet is crucial to preventing diet discontinuation, warranting further investigation into methods for improving palatability, improving the availability and convenience of foods that are compliant with the ketogenic diet, as well as addressing cultural and social acceptance.

The Keto Diet product market may be in a unique position to improve tolerability, especially in social and cultural environments that typically feature carbohydrate-rich “special occasion” types of foods. In 2016, the Paleo Foundation launched the world's first Keto Certified program for products with standards that were developed for adherence to a classical ketogenic diet.
