Ketchup, relish, and mustard walked into a microscope! Our friend Chloe Savard, also known as @tardibabe on Instagram, is back to show us the fascinating microscopic world hiding inside your favorite condiment trio.
Under polarized light, ketchup transforms from a humble staple into a dazzling constellation of suspended particles. What you're seeing is the colloidal suspension that gives ketchup its characteristic texture: tomato cell wall fragments, pectin networks, spice particles, and insoluble solids interacting with polarized light according to their optical properties and internal structure. That riot of color isn't artifice, it's physics. Together, these microscopic structures reveal the complex journey from raw tomato to the smooth, familiar condiment on your plate.
Relish may be an overlooked condiment on the table, but under the microscope it's anything but simple. What you're seeing is a world of cucumber cell wall networks, their honeycomb architecture remarkably intact even after pickling, alongside drifting plant fibers, suspended spice particles, and brine droplets refracting light into iridescent halos. Those four-petaled Maltese cross patterns? That's birefringence, the optical signature of crystalline starch granules interacting with polarized light. Humble hot dog topping. Extraordinary microscopic universe.
Mustard can pack a punch and that holds true at the microscopic level. That vivid yellow fragment at center is a piece of mustard seed tissue, its color coming from curcumin in the turmeric used to make yellow mustard. Surrounding it is a complex emulsion of ground seed husks, starch granules, and oil droplets, while those deep indigo-black streaks are seed coat fragments rich in pigmented phenolic compounds. Mustard's signature heat and pungency come from a chemical reaction between myrosinase enzymes and glucosinolates released when mustard seeds are crushed, and the visual complexity you're seeing under the lens reflects just how much chemistry is packed into every squeeze.
Three condiments. Three completely different chemistries. One very satisfying rabbit hole. 🌭🔬

Among the world's largest science centers and New England's most attended cultural institution, the Museum of Science reaches over 300 million people a year — at Science Park and in museums around the world, in classrooms, and online. Established in 1830, the Museum is home to such iconic experiences as the Theater of Electricity, the Charles Hayden Planetarium, and the Mugar Omni Theater. The Museum influences formal and informal STEM education through research and national advocacy, including through its Youth Exploring Science (YES) program through the William and Charlotte Bloomberg Science Education Center. Around the world, the Museum is known for digital experiences such as Mission: Mars on Roblox and traveling exhibitions such as Science Behind Pixar. The Public Science Common, a state-of-the-art programming and event space featuring sweeping 270-degree views of Boston and Cambridge, and is a space to bring together people for a wide variety of programs and events.
