Heritage beetroot and candied walnut salad

Method

1. Put all the marinade ingredients in a jug and stir well to dissolve the sugar. Peel the beetroot, then slice as thinly as possible into rounds using a mandoline or very sharp knife. Lay in a shallow dish (see tip) and pour over the marinade. Leave for 1 hour at room temperature.
2. Meanwhile, make the candied walnuts. Line a baking sheet with baking paper. Put the 100g sugar in a small non-stick frying pan and cook over a medium heat, swirling, until a caramel forms. Add the walnuts and swirl to coat. Tip out onto the lined baking sheet and allow to cool completely, then break into small pieces with a rolling pin.
