Grown mainly in the Shikoku region, including Kochi and Tokushima prefectures, yuzu is drawing attention as an excellent ingredient that can be used in full—not just the juice but the peel and seeds as well.

The Hidden Value of Yuzu Peel

Yuzu's appeal lies in its distinctive aroma.

The aroma components "limonene" and "citral" contained in the peel's oil sacs not only bring a relaxing effect but also play a major role in adding refined flavor to dishes. Because these components are found more in the peel than in the juice, using the peel lets you draw out yuzu's potential to the fullest.

Its High Nutritional Value Is Not to Be Missed

Yuzu peel is rich in nutrients such as vitamin C, as well as polyphenols. The yellow outer peel with the white part (albedo) removed in particular concentrates components anticipated to have antioxidant effects. These components are said to be useful for maintaining health and beauty, and are now also used as a cosmetics ingredient.

Use as an Act of Environmental Care

As reducing food loss becomes a social issue, using—rather than discarding—parts that are actually edible is essential from the standpoint of environmental protection too. Of the food loss from Japanese households, "parts that are actually edible" such as vegetable and fruit peels account for a considerable share. Using yuzu peel is a practical example of food-loss reduction you can do at the individual level.

5 Ways to Use It in Cooking

Yuzu peel can be used widely not only in Japanese food but also in Western dishes and sweets.

1. Add Flavor as a Condiment

The simplest and most effective use is as a condiment. Just finely chopping yuzu peel or grating it and adding it to clear soup, grilled fish, or chilled tofu brings the dish's flavor alive at once. Scattered over the finished touch of a hot pot, it makes a fragrant accent. Carefully removing the white part in particular lets you enjoy a refined flavor with the bitterness held in check.

2. Homemade Yuzu Salt and Yuzu Kosho

Finely chopping yuzu peel and mixing it with salt completes the all-purpose seasoning "yuzu salt." It can be used on yakitori, tempura, salads, and many other dishes. And "yuzu kosho," made by combining green chili pepper, yuzu peel, and salt, is known as a traditional seasoning of the Kyushu region and pairs superbly with hot pot and noodles.

3. Add Color and Aroma to Red-and-White Namasu

Besides enjoying it as yuzu tea diluted with hot water, it's also delicious added to yogurt or toast. Stored in an airtight container, it becomes a preserved food you can enjoy for several months. Korean yuzu tea (yujacha) is an application of this method.

Points and Tips for Using Yuzu Peel

To use yuzu peel safely and effectively, there are a few points to keep in mind.

Check Whether Pesticides Were Used

When using the peel for food or beauty purposes, we recommend choosing pesticide-free yuzu when possible. If pesticides were used, wash well under running water and use a vegetable wash as needed. In major growing regions such as Kochi, pesticide-free yuzu is also available.

Handling the White Part (Albedo)

The white part of yuzu peel contains a lot of bitter components. When using it in cooking, thinly shaving off only the yellow outer peel gives a refined flavor with the bitterness held in check. That said, when simmering it sweet, as in yuzu jam, using the white part along with it is no problem.

Store It Thoughtfully

Fresh yuzu peel spoils easily, so if you won't use it right away, freezing is recommended. Julienning or finely chopping it and freezing it in small portions lets you take out just what you need when you need it. When drying it, storing it in an airtight container after completely removing the moisture prevents mold from forming.
