Green beans in ginger juice (jiāngzhī dòujiǎo, 姜汁豆角) is one of those Sichuan dishes I’ve come back to again and again since I first made it a few years ago. Tender, crisp green beans are coated in a pungent and refreshing sauce, making a perfect side dish for rich foods. It requires only a handful of ingredients and takes about 20 minutes to prepare. The dish is a variation of jiāngzhī jiāngdòu, 姜汁豇豆, which is traditionally made with snake beans or Chinese long beans (or yardlong beans). But thin green beans, like the kind found in U.S. markets, or French haricots verts make an excellent substitute. 

The dish is a good example of jiāngzhī wèi (姜汁味), or ginger juice flavor, one of Sichuan’s official complex flavor combinations. As the name suggests, this flavor profile puts ginger front and center, highlighting its pungent aroma and sharp, warming heat. Jiangzhi wei is used in both cold and warm dishes, but in cold dishes, the ginger flavor is more concentrated because the ginger is minced or grated and combined with black vinegar, salt, sesame oil and soy sauce (which balance and round out the ginger’s bright spiciness) to make a dressing for vegetables or meat, while in hot dishes the main ingredient is normally simmered or stir-fried before being braised with minced ginger or ginger juice, stock, salt, vinegar and soy sauce.  

Ginger is one of the oldest and most prized aromatics in Sichuan cuisine, and local cooks use it in almost every form: young ginger stir-fried with meat, pickled in the paocai jar, fresh ginger sliced or minced into stir-fries, added to meat marinades and wonton fillings. 

Growing up in Sichuan, I was slow to appreciate ginger myself. As a child, I wasn’t a big fan of aromatics like scallion or ginger. My maternal grandmother, however, was one of those Sichuan home cooks who loved ginger. To nudge picky eaters like my cousins and me toward it, she often repeated a saying: “Eat ginger in summer and daikon radish in winter, and you won’t need to see a doctor” (冬吃萝卜夏吃姜，不找医生开药方).

After I started cooking Sichuan food in my Berlin home, I began to understand how ginger brings a different kind of heat to Sichuan cuisine. While the spiciness of chili is often described as là (辣), the sharp sensation of ginger is called xīn (辛). As the Sichuan food writer Shi Guanghua described it, “The spiciness of ginger hits the heart while garlic hits the mouth and chili hits the stomach.”

How to Make the Ginger Juice (Jiangzhi, 姜汁)

The star of green beans in ginger juice is, of course, the ginger juice. This term can, however, be misleading—sometimes this liquid is the actual “juice” from the ginger root, and sometimes it refers to a sauce that includes a lot of ginger. In Sichuan recipes, there are a few ways to make these mixtures, including smashing, pounding or mincing the root. I’ve also seen ginger blended with water in a food processor. 

In home kitchens, cooks primarily just use minced ginger, cooking it with the other ingredients or using it in a braising sauce (for hot dishes). Another  technique I’ve learned from Sichuan cookbooks, which is especially useful for cold dishes like this one, is to soak minced ginger in black vinegar, a shortcut that draws out the ginger flavor and concentrates it.   

To find out which method works best, I tested three methods for extracting the flavor from the ginger root:

• Mincing: For this method, you need to mince the ginger quite finely, which takes some patience. This method also doesn’t yield much juice, even when the ginger is then steeped in water or vinegar. 
• Grating: This is the best way I’ve found to break down the ginger fibers and extract the juice. First, grate the ginger with a microplane or specialized ginger grater (the kind with lots of tiny teeth designed to break down the fibers, usually used by grating in a circular motion ), then mix it with water and black vinegar. After 10 minutes, you pass the mixture through a fine sieve, pressing the ginger pulp to extract as much juice as possible.
• Purée with a small food processor: Ginger is quite fibrous and dry, so it needs at least 2–3 tablespoons of water to blend smoothly in a food processor. This is the easiest way to break down the fibers and extract the most juice, but the result is more diluted (and you also end up having to wash an appliance). This method makes sense if you’re preparing two or three times the amount called for in this recipe, when using an appliance will cut down significantly on the work required.

In the end, I decided to combine the first two methods, inspired by techniques I’ve seen chefs use in cooking videos. Here’s how you do it: First, peel the ginger. This should only be done right before you use it, because according to the book The Science of Spice, stripping the skin bursts open the outer layer of the cells, allowing fragrant oils to evaporate. The best way to peel ginger is to use the edge of a spoon (which removes skin without taking away much flesh, like a vegetable peeler would). 

Second, grate about 1 tablespoon of the ginger. Mix it with black vinegar and water and let it sit for about 10 minutes, then strain out the fibers, pressing them to extract as much flavor as possible. 

Third, slice and finely mince another tablespoon of ginger, to add to the finished dish. The minced ginger gives the beans a more pronounced flavor and adds crunch, while the ginger juice provides a more subtle aroma in the sauce; together, they provide a nicely rounded flavor. The presentation also looks cleaner than it would if you served the vinegar-soaked ginger on top. 

Because the overall flavor of green beans in ginger juice is refreshing and light, I prefer to use a lighter Chinese black vinegar such as Baoning or Chinkiang to soak the ginger, rather than sharper and more aged varieties such as Shanxi vinegar, which could take over with their strong flavors.

Choosing and Cooking Beans for Green Beans in Ginger Juice

To make this recipe, you can use either yardlong beans from a Chinese grocery store or green beans from a general supermarket. Yardlong beans are thinner and take only about 1–2 minutes to blanch. If I’m using a Western style of green bean, I prefer thin varieties such as French haricots verts. Try to select beans of similar thickness and length so they cook evenly. Whichever beans you use, the goal is to cook them until tender but still crisp, so they provide a fresh contrast to the pungent ginger sauce.

To preserve their green color and crisp texture, blanch the beans only until they are just cooked through but still crisp. Drain them well, season with a pinch of salt and let them cool before dressing.

If you want to make the dish ahead of time, store the cooled green beans and ginger sauce separately and combine them just before serving.
