1.
Wash the vegetables. Peel and dice the onion. Slice only the white part of the leek into rings. Keep the green part and, for example, use it for the pointed cabbage pasta.
2.
Peel the rutabaga and cut into bite-sized pieces. Also cut the parsley root.
3.
Sauté the onion in oil until golden. Add leek, rutabaga and parsley root and sweat, stirring. Add spices except salt and pepper, sauté for one minute and deglaze with 1.5 l of water. Put the lid on the pot and cook over medium heat until the vegetables are soft.
4.
Puree cashew butter with mustard and orange juice in a blender to a thick sauce and transfer to a container/jar. If necessary, dilute with a little water if too thick.
5.
When the vegetables are cooked, remove bay leaves and, if applicable, allspice berries and puree the vegetables (in the same blender, no need to wash out the cashew sauce). To do this, optionally skim off half of the water before pureeing and then add it back afterwards. Add 300 ml orange juice, season with fresh horseradish, orange zest, both peppers and salt. Adjust seasoning if needed.
6.
Warm and froth the barista oat milk.
7.
Divide the soup into coffee cups, not filling them completely. Add 1-2 EL cashew sauce and finally milk foam on top of the soup.
8.
Serve with saucer and coffee spoons like a cappuccino.
