1 kilo bull kelp roots and leaves from the beach
Cover bull kelp with water then simmer for 1 day, we want to remove all the flavour and gelatine from the seaweed. This preparation will turn into a soy sauce-like colour and flavour.
Freeze in a shallow pan, then scrape with a fork to obtain ice flakes. Return to freezer immediately. The snow will be served with the aged fish ceviche.
