Other ya cai substitutes

Ranked, with the exact amount to use

2Zha Cai (Sichuan Preserved Mustard Stem), Rinsed and Minced
Taste and texture differ
Use the same amount rinsed well, plus ¼ tsp sugar per Tbsp
The knobbly salted mustard stem sold in pouches and cans, usually coated in chilli paste.
What changes
Rinse thoroughly to remove the chilli, squeeze dry, and chop as fine as you can.
Best for
dan dan noodles, dry-fried green beans, stir-fried pork, noodle soups, fried rice
Widely available and it delivers the concentrated salt hit correctly, which is half the job. Two things change noticeably. It is dense and crunchy where ya cai is soft and almost crumbly, so the bits stay separate in the sauce rather than melting into the noodles. And it is sharply mustardy and often chilli-coated, so the bowl gains a peppery sting and loses the sweet caramel bass note. Rinse hard and add the sugar; both help more than you would expect.
3Tianjin Preserved Vegetable (Dong Cai)
Different taste
Use the same amount rinsed and minced
Salted napa cabbage cured with garlic, sold in small brown ceramic crocks or vacuum packs.
What changes
Rinse to remove some salt, squeeze dry and mince.
Best for
noodle soups, dan dan noodles, wonton soup, steamed dishes, congee
A good pantry stand-in and easy to find. It is much saltier than ya cai and considerably more garlicky, and it lacks the sweetness entirely, so a bowl of dan dan noodles made with it tastes sharper and more aggressively seasoned, with garlic sitting where the sweet-savoury depth should be. Rinse it well, cut the soy sauce in the recipe by half, and add a quarter teaspoon of sugar to compensate.
4Minced Dried Shiitake Fried With Soy and Sugar
Different taste
Use 3 dried shiitake, rehydrated and minced, plus 1 tsp soy sauce and ½ tsp sugar, for every 2 Tbsp ya cai
Soak the mushrooms in hot water for twenty minutes, squeeze, mince finely, then fry in a teaspoon of oil over medium heat with the soy and sugar until dark and fragrant, about four minutes.
What changes
Best for
dan dan noodles, dry-fried green beans, vegetarian versions, stir-fries
The best option if you have no Chinese preserved vegetables at all, because dried shiitake is a genuine umami powerhouse and frying it with soy and sugar produces the dark savoury-sweet note that is ya cai's whole purpose. It also gives you the right soft chewy texture. What it cannot do is the pickled, faintly sour, fermented aroma that sits behind ya cai and makes the dish smell like Sichuan cooking. Expect a bowl that tastes deeply savoury but slightly one-dimensional.
5Sauerkraut, Squeezed Dry and Fried With Sugar and Soy
Taste and texture differ
Use Half the volume called for, squeezed hard, fried with ½ tsp sugar and ½ tsp dark soy for every 2 Tbsp of ya cai
Squeeze all the liquid out of plain sauerkraut, chop it fine, and fry in oil over medium-high heat until the moisture is gone and the edges brown, then add the sugar and soy.
What changes
Best for
dan dan noodles in an emergency, dry-fried green beans, stir-fries
The honest least-bad option from a Western pantry, and it does not hide. Frying and the sugar and dark soy get you to something dark and savoury, and sauerkraut is at least a salt-fermented brassica, which is the right family. But sauerkraut is sour where ya cai is sweet, and that sourness reads as out of place in a sesame-and-chilli noodle sauce. Use half as much, fry it harder than feels sensible, and taste before you add any more.
6Extra Soy, Dark Soy and a Pinch of Sugar (the omission fix)
Taste and texture differ
Use 1 tsp light soy plus ½ tsp dark soy plus ¼ tsp sugar for every 2 Tbsp ya cai
Do not simply delete the line from the recipe.
What changes
Add the seasonings that were doing part of ya cai's work so the sauce still lands savoury, dark and slightly sweet.
Best for
dan dan noodles, dry-fried green beans, noodle sauces
This is damage control rather than substitution, and it is worth being straight about the cost. Ya cai is the single thing that makes dan dan noodles taste like dan dan noodles rather than a sesame chilli noodle bowl, so its absence is genuinely noticeable to anyone who has eaten the dish before. What you can rescue is the salt, colour and a hint of the sweetness. What you cannot rescue is the fermented aroma and the little dark savoury pockets among the noodles.

What is Ya Cai?

Ya Cai is Ya cai, also written yacai and sold as Yibin ya cai or sui mi ya cai, is the stem and leaf of a Sichuan mustard green that has been salted, sun-dried and then cured for months with sugar and spices until it is almost black, soft, and intensely sweet-savoury.

Cooking tips

Ya cai contributes umami, aroma and a sweet-salty depth. It is not there for crunch, which is the mistake people make when they reach for zha cai as a substitute. In dan dan noodles it is the dark savoury bass note under the sesame and chilli; in dry-fried green beans it is the salty-sweet grit that clings to the outside of each bean. Choose a substitute for flavour depth and accept whatever texture comes with it.
Do not rinse ya cai, unlike almost every other Chinese preserved vegetable. The cure on the outside is the flavour you are paying for. If you find your brand extremely salty, reduce the soy sauce in the recipe instead, or give it the briefest possible pass under cold water and squeeze it dry immediately.
Always fry it before the liquid goes in. Thirty to sixty seconds in a little hot oil over medium heat transforms ya cai from a damp salty crumb into something deeply fragrant, and it is the step most home recipes skip. You will smell the difference clearly. This applies to every substitute on this page as well.
It is very salty, so cut back elsewhere. Two tablespoons of ya cai contribute roughly as much salt as half a teaspoon of table salt, so reduce the soy sauce in a noodle sauce by about a teaspoon when you add it, and taste before seasoning at the end.
Read the label for chilli and for meat. Sui mi ya cai simply means finely minced ya cai and is the same product in a more convenient cut. Some brands add chilli, and a few pack it with pork or with additional flavourings, which matters if you are cooking vegetarian. Plain ya cai is mustard greens, salt, sugar and spices.
A vacuum pack keeps a year or more in the refrigerator once opened, so a single inexpensive purchase from any Chinese grocer or online seller solves this problem permanently. Squeeze the air out and seal it tightly.

Frequently asked questions

Can I just leave ya cai out of dan dan noodles?

You can make the dish without it, but be honest with yourself that it will not taste like dan dan noodles. Ya cai is the ingredient that gives the bowl its distinctive dark fermented savour, and without it you have a good sesame and chilli noodle dish instead. If you have none, add a teaspoon of light soy, half a teaspoon of dark soy and a pinch of sugar so the sauce is at least correctly seasoned and coloured.

What is the difference between ya cai and zha cai?

They come from related mustard plants but are different parts, cured differently. Ya cai is the stem and leaf, salted, sun-dried and cured with sugar for months, so it is soft, dark and sweet-savoury. Zha cai is the swollen stem or tuber, salt-pressed and rubbed with chilli paste, so it is dense, crunchy, sour and mustardy. They are not interchangeable without adjustment: use zha cai for ya cai only if you rinse it and add a little sugar.

Is ya cai the same as preserved mustard greens?

It belongs to that family but it is a specific product, and the generic bags labelled preserved or pickled mustard greens are usually sourer and leafier. The closest relative on the shelf is mei gan cai, sometimes mui choy or mei cai, which is also sun-dried and shares ya cai's dark caramelised character. Choose the sweet version rather than the salty one when you have the option.

Do I need to rinse or soak ya cai before cooking?

No. Unlike zha cai or preserved radish, which are packed in a heavy cure you want to wash off, ya cai's exterior seasoning is the point. Take it straight from the bag, break up any clumps, and fry it briefly in oil. If your brand tastes punishingly salty, adjust the soy sauce in the recipe rather than rinsing away the flavour.

Where can I buy ya cai?

Chinese groceries stock it in small vacuum pouches, often labelled Yibin ya cai or sui mi ya cai, and it is inexpensive. Several online Sichuan specialists carry it as well. If you are shopping in a general Asian supermarket and cannot find it, ask for preserved mustard greens and look for the darkest, driest-looking product rather than a jar of sour green leaves in liquid.
