Yuzu is a Japanese citrus lemon that is valued for it’s highly aromatic rind. Because the yuzu is considered a citron, the juice is very minimal, thus often expensive. Outside of a few Asian cuisines and particularly in Japanese cultural circles, yuzu is seldom grown or used because it’s rather rare.
Used in both green and more ripe, yellow forms, Yuzu is one of the few citrus in the world that is able to maintain it’s tart/sourness at high cooking temperatures.
Yuzu is a sour, tart and very fragrant citrus, slightly smaller than a billiard ball. Yuzu is a citrus that isn’t eaten straight, but is used as a souring ingredient through the use of it’s juice and zest. The flavor is reminicent somewhere between a classic Eureka lemon and an oro blanco grapefruit, but still has its own unique fragrance and flavor. It is a bit more floral and sour and utterly wonderful. It smells so good the Japanese will use yuzu for perfumes and will ritualistically bath in yuzu during Toji (winter solstice).
There isn’t a lot of juice in each little ball of fruit, maybe a teaspoon per yuzu due to much of its mass being occupied by ginormous seeds and a thicker rind. However the juice is one of the very few citrus that can hold up fairly well to cooking without diminishing the flavor. The zest is packed with delicious oils that allow you to use nearly every part of the yuzu in the kitchen.
Yuzu is a integral part to Japanese Ponzu sauce as well as yuzu-kosho, a spicy chili-salt laden with yuzu zest.
For the home gardener, yuzu is one of the most zone diverse citrus, being cold hardy down to 5-10º F. It is a bit stubborn to get to flower and has a few nasty thorns, but it is well worth the time & care to get these beautiful trees to fruit. They are still a bit hard to track down in the United States, but if you have a great nursery nearby, maybe they’ll be able to special order you one.
The fruit is ready earlier than most citrus, usually September or October, giving citrus heavy areas like southern California and Florida extra incentive to add a yuzu to their collections. One of the things we love most about our garden is that there is almost always something fruiting all year. Every season and month has something new to look forward to and it helps ease the grief of another favorite ending for the year.
