Rich, Silky Celeriac Soup

"This recipe is for all the lovers of creamy soup and of celeriac. It not only stars celery root with its earthy flavor, but also a home-made almond cream.It not only stars celery root (celeriac) with its earthy, nutty flavor, but also a home-made cream made of almonds. The cream is easy to make, you only have to soak the almonds overnight, skin them the next day and blitz them with some water in your blender. Of course, if you want to save some time, you can use store-bought vegan cream instead."
