Yuzu kosho is a Japanese condiment that isn't likely to be very well known in the West. Not only are there very few (if any) North American or European brands producing yuzu kosho, but the yuzu fruit from which the condiment is produced can only be grown in the most temperate regions of California. Nonetheless, this Japanese yuzu kosho condiment from Earthly Delights offers a unique combination of citrus and spice that can improve many dishes.
In the West, condiments tend to be based around three standards: ketchup, mustard, and mayonnaise. Even with flavors added into these, the possibilities are relatively limited. For most people, yuzu kosho is an entirely new condiment that offers a different range of palette options, expanding the potential for new dishes and meals.
