Have you ever tasted the unique blend of sour and salty in a pickled plum onigiri?
Finding the right balance of flavors and techniques for making these delightful Japanese rice balls can be tricky.
Pickled plum onigiri, or umeboshi onigiri, combines Japanese short-grain rice and umeboshi (pickled plums) for a delicious, tangy snack.
In this guide, we’ll walk you through the essential ingredients, step-by-step preparation, storage tips, and creative variations to help you master the art of making perfect pickled plum onigiri.
Essential Ingredients for Making Pickled Plum Onigiri

Making pickled plum onigiri starts with selecting the right ingredients. The foundation of this traditional Japanese snack is steamed rice, specifically short-grain Japanese rice known for its sticky texture that holds the onigiri together. Umeboshi, the pickled plums, are essential for their unique sour and salty flavor. These plums are often seasoned with red shiso leaves during the pickling process, adding a deep red color and a hint of minty flavor.
Other ingredients include nori sheets, which wrap the rice ball, providing a crisp texture and a sea-salty taste. A pinch of salt is also used to season the rice and enhance the overall flavor. For those looking to add a subtle nutty taste, white sesame seeds can be sprinkled on the rice before wrapping it with nori. Each ingredient plays a crucial role in creating the perfect balance of flavors and textures in pickled plum onigiri.
Nutritional Benefits of Pickled Plum Onigiri
Pickled plum onigiri not only delights the taste buds but also offers significant health benefits. Umeboshi, the key ingredient, is known for its digestive and detoxifying properties. These plums are rich in citric acid, which helps in fatigue recovery and boosts metabolism. Additionally, umeboshi has been found to have properties that may suppress the growth of harmful bacteria, such as Helicobacter pylori, known to cause stomach issues.
Nutritionally, each onigiri contains about 129 calories and provides a good source of carbohydrates and protein, essential for energy. Despite their sour taste, umeboshi are surprisingly a low-sugar option, making them a suitable snack for those monitoring their sugar intake. The inclusion of nori adds minerals like iodine and vitamins, enhancing the nutritional profile of the onigiri. Thus, incorporating pickled plum onigiri into your diet can be a tasty way to enjoy a range of health benefits.
Step-by-Step Guide to Preparing Pickled Plum Onigiri
Preparing pickled plum onigiri starts with the right setup. First, ensure you have all necessary ingredients: Japanese short-grain rice, umeboshi (pickled plums), and nori seaweed sheets. Cook the rice until it’s sticky and slightly cool to the touch, which is essential for forming stable onigiri.
Next, prepare your umeboshi by removing the pits, if they are not already pitted. Place a small amount of rice in your palm, and press the umeboshi into the center. This sour plum is the heart of the flavor, so it’s important to center it well within the rice.
To shape the onigiri, scoop more rice over the umeboshi to cover it completely. Press and mold the rice with your hands into a triangle shape. Remember, the key is to apply firm pressure to ensure the rice sticks together without smashing the grains. Finally, wrap the shaped onigiri with a strip of nori seaweed for a crispy, salty finish.
Pro Tips for Perfecting Your Pickled Plum Onigiri
For those looking to elevate their pickled plum onigiri, consider these pro tips. Firstly, use freshly cooked rice as it sticks better and tastes superior. For an aromatic touch, mix a few shiso leaves into your rice before shaping. Shiso adds a unique flavor that complements the umeboshi well.
Additionally, for a textured contrast, sprinkle some sesame seeds on the rice before wrapping it with nori. Not only do they add a nutty taste, but they also provide a delightful crunch. Always ensure your hands are wet when shaping the onigiri to prevent the rice from sticking to your hands, making the process smoother and cleaner.
Creative Variations of Pickled Plum Onigiri
To add a twist to the traditional pickled plum onigiri, consider incorporating additional ingredients that complement the tangy flavor of umeboshi. Some popular variations include:
- Ume Wakame Onigiri: Adding wakame (seaweed) to the rice mix enhances the oceanic flavor.
- Ume Goma Onigiri: Sprinkling toasted sesame seeds offers a nutty crunch.
- Ume Agedama Onigiri: Including agedama (tempura bits) introduces a delightful crispy texture.
For those who enjoy a more intense flavor, Ume Miso Yaki Onigiri involves spreading a mixture of umeboshi and miso on the onigiri, then lightly toasting it. This method adds a rich umami taste and a slightly charred texture. Another creative option is Ume Takuan Onigiri, which incorporates takuan (pickled daikon radish), adding a sweet and crunchy contrast to the sour umeboshi. These variations allow for a personalized touch to your onigiri, making each bite a new experience.
Storing Your Pickled Plum Onigiri Properly
To maintain the freshness of your pickled plum onigiri, proper storage is crucial. Ideally, wrap each onigiri individually in plastic wrap to create a moisture barrier that keeps the rice soft and prevents it from drying out. This method also helps to preserve the distinct flavors of the umeboshi and rice.
After wrapping, place the plastic-wrapped onigiri in a refrigerator where they can stay fresh for up to three days. Remember, the cooler environment slows down any bacterial growth and keeps the onigiri safe to eat. For best results, consume them within this time frame to enjoy their ideal taste and texture.
Mastering Nori Wrapping for Pickled Plum Onigiri

Wrapping your pickled plum onigiri in nori (seaweed) not only secures the rice shape but also adds a crisp, oceanic flavor that complements the tangy umeboshi. Begin by laying a half sheet of nori on a clean, dry surface. Place the shaped onigiri on one end of the nori sheet, ensuring the broader base of the triangle faces down. Then, gently wrap the nori around the onigiri, slightly stretching as you wrap to keep it snug.
For an aesthetically pleasing finish, you can experiment with different nori wrap styles. Here are a few popular ones:
- Full Wrap: Completely encase the onigiri in nori, covering all sides for a uniform look.
- Band Style: Wrap a single strip of nori around the middle of the onigiri, leaving the top and bottom exposed.
- Diagonal Wrap: Place the onigiri diagonally on the nori and fold the corners up, creating a neat, angular design. Each style not only changes the look but also the texture and nori-to-rice ratio in each bite, allowing for a customizable eating experience.
What to Serve with Pickled Plum Onigiri

When planning a meal around pickled plum onigiri, consider pairing it with dishes that complement its unique flavor profile. A light miso soup can provide a soothing balance to the tangy umeboshi, while a side of tamagoyaki (Japanese omelette) adds a sweet and fluffy contrast. For a refreshing touch, include a cucumber salad dressed with rice vinegar and sesame seeds. These side dishes not only enhance the meal but also ensure a well-rounded nutritional intake.
As for drinks, green tea is a classic choice that pairs beautifully with the salty and sour notes of pickled plum onigiri. The subtle bitterness of the tea helps cleanse the palate between bites. For those preferring a cold beverage, a chilled barley tea or even a light Japanese beer can be delightful. These drink options help to create a harmonious dining experience, making your pickled plum onigiri meal both enjoyable and memorable.
