Yuzu kosho is a sour, salty, and citrusy Japanese condiment. I first encountered it on top of nigiri sushi. But it’s a versatile ingredient that can be used in many applications like salad dressing and even margaritas.
Yuzu kosho is easy to find online and at Japanese grocers. But it’s not hard to make at home either.
Armed with some fresh yuzu and serrano, I used a recipe from Kiel Kleeburg for my first attempt. And the results didn’t disappoint.

- Once you’re happy with the flavor, store it in the refrigerator.
- Your yuzu kosho should last six months to a year.
About Yuzu
Yuzu is a citrus variety from Japan. It has an extremely aromatic peel, and a floral scent, and tastes like a combination of pink grapefruit, Meyer lemon, and mandarin orange.
If you don’t have yuzu on hand, I recommend a combo of these fruits.
Sudachi is arguably the most suitable substitute. However, outside of Japan, it’s even harder to find.
