For the dressing: Place all the ingredients into a jar and shake well until combined.

1. Bring a small pan of water to the boil and add the white vinegar.
2. Crack eggs into a glass, one at a time and tip into the just-boiling water.
3. Poach for 2-3 minutes, with a slotted spoon remove the eggs gently and drain on paper toweling. Season with salt.
4. To assemble the salad, arrange frisee into a shallow bowl. Add the smoked duck, croutons, a poached egg, walnuts and a sprinkling of chives.
5. Finally drizzle with the dressing.
