Head to just about any hotel breakfast buffet in Japan, and you'll be greeted with some unique options. Menu items like miso soup, grilled salmon, and pickled veggies are often par for the course, but if you're after something more Western-inspired, you'll typically find bread and jam available too. One type of jam option you may not have tried before is yuzu jam (sometimes referred to as yuzu marmalade), which is made from this prolific citrus fruit with East Asian origins.
Uses for Yuzu Jam
Yuzu jam can be used in a variety of ways, as you would with regular marmalade – for instance, on bread or scones. This online recipe also recommends it to enhance sauces like teriyaki sauce for a bit of extra zing.
In Korea, yuzu jam is commonly mixed with hot water to make what's called yuja-cha, or yuzu tea (yuja is the Korean word for yuzu), so if you're after a warming drink for the winter months be sure to give it a try.
More about yuzu
Yuzu growing in Tokyo
Tokyo's Tama region is the center for yuzu growing in the prefecture, with orchards in Ome, Akiruno, and Hachioji to name a few. There is even a specific yuzu species native to the Ome area - it's the Sawai yuzu, which is characterized by its thick skin, rugged appearance, and incredible scent.
Yuzu outside of the greater Tokyo area
The number one prefecture for yuzu production is Kochi -- in fact, they account for 52% of Japan's national yuzu supply! This JapanTravel tour shines a spotlight on not just yuzu but some other of Kochi's food specialties if you're interested in learning more.
Finding yuzu jam outside Japan
Amazon is always an easy way to find international products, and they do stock yuzu jam - although it's at quite a markup to what you'd expect in Japan. Checking at Asian grocers is also recommended, and along with yuzu jam you can often find other products containing yuzu such as ponzu, a citrus-based sauce which is often used in Japanese cuisine.
