Authentic Yuzu Kosho Recipe

Equipment
- Suribachi or Mortar and Pestle
- Glass jar
Ingredients
- 150 g yuzu peel, fine mince
- 150 g jalapeno, fine mince
- 30 g sea salt
Instructions
Prep the Yuzu Peel
- Peel the yuzu by hand, aiming for the fragrant outer zest and as little white pith as possible. The aroma should be intensely floral and citrusy, like you just rubbed the peel between your fingers.
- Use a spoon to scrape away any remaining white pith until the peel looks mostly clean and thin, then mince it very finely. This is where bitterness sneaks in, so take your time and make it neat.
Prep the Jalapeno
- Split the jalapenos and remove the seeds, then mince the flesh finely so it blends evenly with the zest. If you want to keep your hands happy, gloves help, and a thorough soap wash afterward is non-negotiable.
Pound Into a Fermentation-Ready Paste
- Combine the minced yuzu peel and minced jalapeno with the 30g sea salt. At this moment, stir in the 1/2 teaspoon finely powdered kombu and add a tiny splash of fresh yuzu juice, you will feel the mixture loosen slightly as the salt begins to dissolve.
- Pound the mixture in a mortar and pestle, ideally a ridged Japanese suribachi, working in batches if needed. You are looking for a cohesive mash that looks glossy and smells loud, citrus oil up front with a savory ocean whisper from the kombu.
Pack and Store
- Spoon the mash into a clean jar and pack it down firmly so it sits tight with minimal air pockets, then store it in the fridge or freezer. The flavor will mellow and knit together as it rests, becoming more rounded and deeply aromatic.
Notes
Equipment Tip: For the best texture and essential oil release, use a traditional suribachi or heavy mortar and pestle instead of a food processor, which tends to chop rather than crush the ingredients.
Bitterness Prevention: Always take the time to scrape away the white pith from the yuzu peel before mincing, as this is the primary cause of a bitter paste.
Safety First: Wear gloves when handling and mincing the jalapenos, and wash your hands thoroughly with soap immediately after to prevent capsaicin burns.
Fermentation Rule: Stick strictly to non-iodized sea salt. Iodized table salt can inhibit the beneficial lacto-fermentation process and leave the flavor feeling flat.
