    Place the butter in a pan and clarify - melt slowly, allowing the fat to separate from the water and milk solids. Skim off the foam that rises to the top.

    Pick the leaves from the tarragon and parsley. Chop the leaves making sure not to bruise the tarragon. Reserve the tarragon stalks.

    Peel and finely dice the shallot. Place in a pan with the tarragon stalks, dry white wine and vinegar. Allow to reduce to a fifth of the original volume then remove from the heat and pass through a fine sieve.
