Pass the juice, add the cream, season with Maldon salt, and add the butter gradually with a hand blender.
For the tiny Tokyo turnips and turnip slices:
Was well and remove any excess outer leaves. Take the remaining large turnip and slice thinly on a mandolin, using a metal cutter to create 2” discs. Prepare a 30% butter 70% water emulsion seasoned well with salt to cook them in.

Warm the turnips discs and tiny turnips in the butter emulsion and arrange over the scallop, warm and aerate the sauce slightly and use to cover, warming the raw scallop, garnish with the small anise hyssop leaves and puffed pearl barley.
