A delicious, hearty soup blending the flavours of potatoes and apples with lemon juice, wine, chicken stock, arugula and herbs and spices. I always use Granny Smith apples and I have often used a mix of potatoes and sweet potatoes. The original recipe specifies “waxy potatoes” but this didn’t correspond with any of the potato varieties listed in the Zaar kitchen dictionary. Use a variety that you know works well in soups. I have also experimented with different herbs and spices. Vary herbs and spices to suit your preferences. Adapted from the English recipe book 'Potatoes and Vegetables' by Parragon Publishing.
