This ravigote sauce recipe by Henry Harris is a true French classic. Made in a similar way to mayonnaise, but with Dijon mustard and no eggs, it is a truly delicious sauce. Serve with delicately flavoured meat and fish.
Vigorously whisk the oil into the mustard mix, pouring in a thin, steady stream. Once thick and emulsified, stir in the remaining ingredients and adjust the seasoning to taste, adding a dash more vinegar if necessary
