Cut the butter into equal cubes and store both in the refrigerator until needed.
Let the white wine, sake, dashi vinegar and matured soy breathe a little until the alcohol has evaporated.
Add the lightly whipped cream and knobs of butter, and cook over a medium heat until all the butter has melted.
Leave to rest for 5 minutes on the side of the stove.
Add the coral and mix with a hand blender until you get a stable and thick emulsion.
Season with salt, if necessary.
