For the ayu mousse, preheat oven to 180°C. Rub ayu bones and head with some oil and salt. Roast until golden brown. Process into a powder. Whisk egg whites until stiff peaks. Process ayu fillet with pork fat and ice cubes to obtain a fine mousse. Mix in whisked egg whites and ayu bone powder by hand. Season with salt. Spread ayu mousse onto deboned ayu and roll into a cylinder. Steam at 85°C (185°F) for a few minutes before grilling over a charcoal grill until fragrant. Set aside.

For the sake gel, combine water and agar agar in a bowl. Place 80 g (24/5 oz) of mixture with sake in a food processor. Set aside. Prepare miso cream. Beat egg yolk, grape seed oil, argan oil and salt until thickened. Season with lemon juice. Mix with miso paste. Rest for 1 hour before using.

For the fish fumet, bring ayu bones, kombu and cold water to a boil in a large pot. Lower heat and simmer for 10 minutes. Remove kombu and add baby silver herrings. Cook for 30–40 minutes. Strain stock.

For the silver herring paste, drain silver herrings and pat dry with paper towel. Heat 1 Tbsp oil in a pan over medium heat. Sauté silver herrings until fragrant and golden brown. Drain excess oil. Combine with fish fumet and squid ink in a food
processor to obtain a paste. Set aside.

For the yamazeri purée, bring water to a boil in a large heatproof bowl. Add salt.
Place yamazeri leaves and salted water in a food processor to obtain a smooth purée.
Slice grilled ayu and arrange on serving plates. Drizzle with yamazeri purée, and serve
with sake gel and silver herring paste. Garnish as desired.
