Ingredients
Pickling liquid
Salad
Dressing
Method
1.Combine all pickling liquid ingredients in a small pot and bring to the boil. Simmer for 5 minutes, then strain into a bowl. Add the sliced mushrooms, mix well and leave to infuse for 30 minutes.
2.Cut the cooked potatoes into 1cm slices. Heat butter in a large stainless-steel frying pan until sizzling, then toss in the shallots and sweat on medium heat for 2–3 minutes. Add the bacon, cook for 2–3 minutes or until the bacon is crisp, then mix in the sugar. Add sliced potatoes, cook for 2 minutes, mix well, then transfer to a large bowl. Season with salt and pepper, then add the chives and the watercress.
3.Whisk together all the dressing ingredients.
4.Drain pickling liquid from the mushrooms and mix mushrooms into the potato salad. Pour dressing over the salad and serve. (The pickling liquid can be saved to use again – for instance, to pickle julienned cucumber or finely shaved fennel.)
