The strengths are editorial judgments on a scale within the family, not measurements. They can be compared across the spices and yakumi varieties, not directly against another family.

Origin Kyushu

Yuzu kosho is grated yuzu peel, chili, and salt, fermented into a paste, and the family's only spice that is salty in itself. The name misleads: kosho means black pepper in standard Japanese, but in the dialects of Kyushu it means chili, and that is where the product comes from. A small dab delivers citrus aroma and heat at the same time, which nothing else in the family does.

Background

Facts

Origin
Kyushu, with Hita in Oita and Soeda in Fukuoka as the places usually singled out, both yuzu-growing districts
The name
kosho means black pepper in standard Japanese but chili in the Kyushu dialects, so the name reads literally as yuzu and pepper but means yuzu and chili
Contents
grated yuzu peel, chili, and salt, left to ferment; the salt is both preservation and flavor
Variants
green is made from unripe yuzu and green chili and is sharper and more herbal; red is made from ripe yuzu and red chili and is fruitier, with a rounder heat
Use
nabe, grilled meat, sashimi, noodles, and miso soup; a dab at a time, like mustard and not like a sauce

At the table

Use

Dosage
half a teaspoon per serving; the salt means more quickly becomes too much
Timing
added to finished food or stirred into a dip; the citrus aroma disappears in boiling
Note
keep it refrigerated after opening, and it holds its aroma longer if the spoon is dry every time
