1 teaspoon Atlantic sea salt
1 tablespoon organic butter

1 teaspoon organic tamari
1 black winter truffle

Carefully peel the onions, and cut a little larger than half way along the grain.
Lightly salt then sweat the onion trimmings in butter. Once the trimmings have caramelised lightly add water, Kombu and Bonita flakes then boil for 1 minute.
Place whole onions root side down and upright in the cooking liquid. Cook for 12 to 14 hrs at a low temperature with a heavy lid occasionally basting.
Add black truffle slices for final 20 minutes of cooking. There should be 5 tablespoons of cooking liquid remaining.
Add 1 tablespoon of cooking liquid to a warm bowl then carefully place 1 onion and add a little grated cheese.
Add olive oil to remaining liquid and baste the onions.
Shave white truffle over the top.
