Zhima Jiang: A Field Guide for Curious Eaters
Zhima jiang (芝麻酱, pronounced roughly “jrr-maa jyang”) is the toasted-sesame paste that runs through northern Chinese cooking like a bassline — the thing Beijingers stir into hot pot dips, cold noodles, and steamed buns, and the secret behind half the “that weird brown sauce” moments travelers have in China. For the wider landscape of what you’ll eat on the road, our Chinese food guide is the place to start. If you’ve only met tahini at a Mediterranean deli, understand this first: zhima jiang is its darker, toastier, faintly bitter cousin, made from sesame seeds roasted until they smell like popcorn before they’re ground into a paste. I didn’t get it on my first trip. Then a Beijing friend dragged me to a hot pot joint on a freezing February night, the sauce hit my tongue, and it quietly changed how I order Chinese food. This is the field guide I wish I’d had beforehand: what it actually is, how locals really eat it, where to buy a jar without overpaying, and the rookie mistakes I made so you don’t have to.
What zhima jiang actually is (and why it is not tahini)
The name breaks down simply: zhi ma is sesame, jiang is paste or sauce. You’ll also hear it called majiang (麻酱) — drop the “zhi” and you’re speaking like a Beijinger — and, because the hot-pot style dominates the north, sometimes “north sauce” (北酱). At its core it’s one ingredient: roasted sesame seeds, ground until the natural oils turn them into a thick, spoonable paste. No sugar, no thickeners, just sesame. The good jars list a single ingredient.
Here’s the part that trips people up. Walk into any Asian supermarket and you’ll see “sesame paste” and “tahini” sitting a shelf apart, and they are not interchangeable. As SBS Food puts it, zhima jiang is made from sesame seeds “heavily roasted,” which is what gives it a deep roasted flavour “similar to peanut butter, but with significant sesame punch.” SBS Food — Move over tahini, have you tried zhi ma jiang? Tahini, by contrast, uses hulled, raw or lightly toasted seeds, so it stays pale, mild, and pourable. Zhima jiang is darker than peanut butter, thicker, and carries a slight natural bitterness that tahini never has.
I learned this the hard way. On trip one I substituted tahini into a cold-noodle recipe I’d noted down, and it tasted like a stranger had made the dish — sweet, flat, missing the toasty backbone. The fix isn’t more tahini; it’s the real thing, or at minimum a lightly toasted tahini plus a drizzle of toasted sesame oil.
How I first met it: Beijing hot pot
The cleanest introduction is a Beijing copper hot pot (涮羊肉, shuan yang rou) on a cold night. The broth is deliberately plain — often just water with scallion and ginger, sometimes a whisper of lamb bone — because the point is the lamb, not the soup. What carries the flavour is your personal dipping sauce, and its foundation is always zhima jiang. You thin a lump of it with a little broth or water until it’s the consistency of loose yogurt, then build from there: a dab of fermented tofu (furuko) for salt and funk, chive-flower sauce for pungency, fresh chili oil, minced garlic, scallions, cilantro, a splash of vinegar to cut the fat.
Beijingers talk about the “er ba jiang” (二八酱) ratio — roughly 80% sesame paste to 20% peanut butter — which softens the bitterness with a little sweetness. When I finally nailed my own bowl at a place off Niu Jie, I understood why locals guard their sauce recipes like family heirlooms. New to the table? Here’s how to use chopsticks without looking like a tourist. The first bite of lamb, straight from the pot, rolled through that nutty, funky, cooling sauce, was the moment the paste stopped being abstract and became something I’d crave. For background on the ritual and where to eat it, Wander in China has a solid walkthrough of the broth, the sauce, and the classic spots like Ju Bao Yuan and Dong Lai Shun.

The cold-noodle revelation
If hot pot is the winter version, cold sesame noodles are the summer one, and honestly the easier habit to bring home. In Beijing the dish is zhima jiang ban mian: chewy wheat noodles rinsed cold, a generous scoop of sesame paste, soy sauce, rice vinegar, garlic, shredded cucumber, and optionally chili oil. You stir like you mean it — the paste starts stubborn and clumpy, then loosens into a creamy coating on every strand. On a 35-degree-Celsius August day, it’s the lunch half the city reaches for.
What surprised me was how forgiving it is. Too thick? A splash of vinegar or the noodle cooking water. Want more punch? More garlic, a little more soy. The paste does the heavy lifting, so even a timid cook produces something that tastes like Beijing. I now keep a jar purely for this — it’s the one recipe from the trip I make monthly, and it travels better than any souvenir.
White vs black, and the peanut blend
Two main pastes sit on the shelf. White sesame paste (白芝麻酱) is the everyday one — the hot pot base, the noodle sauce, the bun filler. Black sesame paste (黑芝麻酱) is earthier and slightly more bitter, and in China it’s mostly pointed at sweets: black sesame soup (芝麻糊), filled buns, ice cream, even a drizzle over vanilla. I’d file white as “cook with it,” black as “dessert with it,” though plenty of households mix the two.
Then there’s the peanut blend you’ll meet at hot pot restaurants and in economy jars — sesame paste cut with peanut butter for a smoother, sweeter scoop. It’s delicious and cheaper, but read the label if you have a peanut allergy, because some brands run the blend high. Travelers with food sensitivities should also skim our China food safety guide before ordering. My rule: buy pure sesame for cooking, enjoy the blend when a restaurant hands it to me.
Where to buy it, and what to pay
In China the cheapest, freshest option is a wet market or supermarket with a live stone mill. I watched one outside Beijing grind jars to order: white sesame paste around 19.8 yuan per jin (a jin is 500g) and black around 22.8 yuan per jin, glass bottle free, back in 2019 — roughly four dollars a pound for the real, fresh stuff. Zunyi Evening News — supermarket stone-mill sesame paste (2019 prices) That’s the version to hunt for: you can taste the oil is alive.
Packaged brands are everywhere and easy to trust. Look for Liubiju (六必居) and Wangzhihe (王致和) — old Beijing names — plus Lee Kum Kee and Koon Chun for pantry staples. Outside China, a 225g jar of Wangzhihe runs about £2.35 at UK Chinese grocers, and US Asian supermarkets and apps like Weee list Li Kam Kee and Wangzhihe jars in the $3–$13 range depending on size and brand.

Tasting Table — What Is Chinese Sesame Paste
One lovely bit of history: behind the Drum Tower in Beijing, the Zhao Fu Jie food store has scooped sesame paste from a vat since 1956, back when it was rationed to about 50 grams per person per month. My Beijing friend’s parents still speak of queuing with a ration book. The store is a working museum now, and if you’re in the neighborhood, watching them ladle paste into your own jar is worth the detour. Matador Network — Beijing’s sesame sauce
My mistakes, so you skip them
First: I stored the jar in the cupboard. The oil separated into a hard disc on top and a stiff paste below, and it took real elbow grease to bring back. Now I refrigerate after opening and let it sit on the counter 20–30 minutes before use, stirring from the bottom. Second: I assumed “sesame paste” on any label meant zhima jiang and once bought a sweetened, thickened imposter for a savory dish. Check the ingredient list — pure sesame, maybe salt, nothing else. Third: I overdid the paste in a dressing and it turned chalky. Thin it gradually with warm water or broth; you want loose yogurt, not mortar.

FAQ
Is zhima jiang the same as tahini?
No. Both come from sesame, but zhima jiang uses deeply roasted (often unhulled) seeds, making it darker, toastier, thicker, and faintly bitter, while tahini is made from hulled, lightly toasted or raw seeds and stays pale and mild. Don’t swap them one-for-one in recipes.
What do Chinese people actually eat it with?
Mostly as a hot pot dipping base in the north, as a cold-noodle sauce in summer, and as a filler for steamed buns and pastries. Black sesame paste goes into sweet soups, buns, and ice cream. It’s a pantry workhorse, not a condiment you use by the drop.
Can I make it at home?
Yes, and it’s cheap. Dry-toast white sesame seeds in a pan until fragrant and deep golden, cool, then blitz in a food processor with a little toasted sesame oil, adding oil slowly until it forms a thick, glossy paste. Homemade keeps at least a month in the fridge.
How do I thin it for a sauce?
Whisk in warm water or broth a teaspoon at a time until it’s the texture of loose yogurt. Water lightens the flavour; sesame oil keeps it rich. Always stir the jar from the bottom first, because the oil rises to the top as it sits.
Is it healthy?
It’s energy-dense — mostly fat and protein from sesame, with calcium and iron — so treat it as a flavour builder, not a free pour. I’m not a nutritionist and this isn’t medical advice; enjoy it as part of a normal diet.
Bottom line
Zhima jiang is one of those ingredients that’s invisible until you taste it properly, and then it explains a hundred dishes you’ve had in Chinese restaurants. Buy a pure-sesame jar, thin a spoonful into a hot pot dip or a bowl of cold noodles, and you’ll get why Beijingers guard their sauce ratios. Start with the white paste for cooking, keep the black for sweets, refrigerate it, and stir from the bottom. The rest is just practice — and a very good excuse to eat more noodles.
